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.

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?

Well, you mention you,re going to the states, there couldnt be a better opportunity while the dollar is the best its been, you could bring them home in suit cases, looks like a golden opportunity to me.

There have been no problems with fitment of the Dove or Harland Sharp roller rocker arm assemblies under the stock or Thunderbird valve covers to date.

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.

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-----
