Are they side specific? What I mean is, I see in the rocker boxes there's a number cast in the middle. One has a "1" and the other has a "2". Reason I ask is I just had new guides installed as well as the seats/valves resurfaced as well as the head sealing surface.

Now after installing the heads and trying to set the valves, I've had to back the adjusters waaay off just to get the rocker shaft/rockers back on. This doesn't seem normal to me, and I double checked to make sure the pushrods are seated correctly in the lifters. Am I missing something here?

Help! I want to put this car back together and enjoy it!

did you check your deck height and compression?

if its high, you may be able to compensate using shims under the barrels.
This can help correct changes in geometry due to flycutting.


Were the heads flycut? how much?
Were they valve jobbed? did they install new seats?

both of these operations can effect the height of your valve stem, and the amount of adjustment you have left on your rocker adjuster.


I wouldn't try to set the geometry until you know your compression is where you want it.

Then its a function of cutting pushrods and shimming rockers, but not as simple as that. (IMG:style_emoticons/default/biggrin.gif)
