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.
