Planing on getting the Dove Roller Rockers. Talked with them last week. They apparently have 3 different rocker arms. Right offset, left offser, and no ofset. Need to know what combination of these I will need with the Mummert heads and also I need special pushrods. I have the Ford heavy duty welded tublar pushrods now.

Go to rockerarms.com. They make a rocker arm setup just for the Mummert heads. It includes all instructions and extra hardware. Gary, can answer any and all questions on this setup and rebuilt stock units. They have 1.4, 1.5. and 1.6 ratio rockers with the correct offsets.

On the Dove rockers for the aluminum heads, you’ll need 6 rockers with centered adjusters, 6 rockers with left orientated adjusters, and 4 rockers with right orientated adjusters. If you go the Dove route and they don’t include a instruction sheet, just email me directly and I’ll send you the sheet I use. I don't recall the pushrod length offhand for the Dove's but the pushrod length for the Harland Sharp roller rockers is 8.000" effective length for the aluminum heads.

There have been some problems with the Dove breaking and the balls not hardened, or overhardened so they are brittle and breaking. You may want to go the Harland Sharp route, I don't think they sell shafts and I think Ted can set you up with them.

I have Dove rockers and have not had any problems with them. I do recall someone on here having issues but he is the only one I have heard of. Any one else had problems?

I had them early in the piece and had poor oiling characteristcs, Ted grooved the shafts to overcome similar problems, i had since removed them had no problems.

Thank you all for the input. I was not familiar with Rockerarms.com but like what I see on there website. I like the idea of instructions and the fact that they know exactly what is required for the Mumert heads. Dove refered me back to Mummert or Ted Eaton for which ones it took. Dove also insisted that solid spacers were requried. I have had the stock rocker arm set up to 7,000 at least a few times and no problems. I will call Rockerarms.com Monday and talk to them. Did not see prices on the website. Anybody know about what they run? Dove is not cheap but not what I consider totaly out of sight.

I have had a very early set of Dove 1.6 roller tip rockers for since 1998 and they have been rock solid. They are all centered no left or rights in those days. It took quite a bit of working in the pushrod holes of ECZ-G heads to get the rollers to center on the valve stems and washers to space them along the shafts. Mine are held in place with sleeves on the shafts. Also I grooved the rocker bores slightly to conduct oil from the hole in the bottom of the shaft part way around to oil the ball and the other way to oil the valve stem and roller. The holes were there and but the rockers are a very tight fit on the shaft and it was obvious that there was no way for the oil to get out of them. I sort of doubt that Dove had ever had a set on a running engine at that time. I also pressurize the shafts with a restriction in the U pipe. There is flow to the dist gear and timing chain but pressure in the shafts.
I think that one of the differences in John M's Al heads is in the pushrod hole so it may be that you must use the Rocker Arm specialist rockers.

Getting partial sets or individual Y rockers from Dove is not expected to be a problem. Just give them a call and talk to them concerning your needs. If there is a problem in doing this, just give me a shout and I’ll see what I can do. The aforementioned problem with the Dove adjusters breaking was with a particular batch of adjusters made from improperly heat treated material. While it was embarrassing for Dove that this happened, they went out of their way to supply me an adequate number of correctly heat treated adjusters so that I could get with customers and get those faulty adjusters swapped out. That issue hasn’t surfaced in quite awhile now. The Harland Sharp roller rocker setup for the aluminum heads uses the same number of adjuster offsets as the Dove units. The setup on the shafts ends up being similar. For the aluminum heads, I am having to machine 0.080” off of one side of the second from the right supplied rocker stand in order to maintain proper valve stem tip alignment. Not a biggie on this end as I perform that operation in a lathe which also allows me to put the step back on the edge of that particular stand for rocker side clearance. Regarding using solid spacers or springs between the roller rockers, I’ve been both ways. For whatever reason, the rocker assemblies using springs appear to have a slight horsepower advantage over the rocker assemblies using spacers. Having a slight preload on the rockers seems to work in favor of controlling some unwanted movement in that area. Here’s a picture of the Dove Rockers on the aluminum heads. This particular set is using spacers between the rockers.  Here’s a picture of the Harland Sharp rockers on the aluminum heads. This particular set uses springs between the rockers.

Great photos. I am assuming that the T-Bird valve covers will fit with the Dove setup? One more question. Is drilling the holes in the block and heads for cooling between the middle cylinders advisable with the aluminium heads?

I’m going out of my way to plug the holes in the blocks when they are present. On my end, no steam hole venting is required with standard height radiators. Here are links to a couple of other threads on the subject. http://forums.y-blocksforever.com/Topic18743.aspx http://forums.y-blocksforever.com/Topic47206.aspx Performing a search will bring up more on the topic.

For my .02 cents worth the spacers are a lot of trouble getting the side clearance required between them. Then if you take the assembly off and put them back on you have to fiddle around as you bolt them back down to get the side clearance right again. More HP with springs and no shimming sounds like a no brainer to me.

Planing on going with the springs. Hope to call Dove tomorrow and order them. When I talked to them a week or two back they were out of stock but planed to have them soon. As always, great information here. Thanks to Ted and everyone else. Now if I can just figure out the piston rings-----

At the risk of sounding like a commercial, $565 + shipping for the Harland Sharp ‘ready to run’ assemblies as provided by my shop. But I am one of the few shops doing the Harland Sharp rockers for the Y engines. For the iron heads, this includes new shafts and the factory stands. For the aluminum heads, the customer will need to provide the specialized rocker shaft support stands that are included with the new heads. Due to the rockers needing final clearancing for proper fitment to the shafts, Harland Sharp is currently referring all potential Y customers to shops that can insure that the rockers are final honed and assembled correctly depending upon the cylinder head being used. Just email me at “ted at eatonbalancing dot com” if more details are needed.

I checked Harland Sharp's website and could not find any reference to Y Blocks. Must be overlooking the obvious. I am a little concerned about having to have them custom fited by a shop. Dove seems to be end user installabile with instruction. Cost is an issue but I am more concerned with what will work and what I can easily install and service after the fact myself. I am thinking any of the mentioned roller rockers will work and improve performance.

Teds deal sounds good, I am going to work on getting my Dove setup for the oem heads to fit. Toys are getting pricey now.
