Almost time for the machinist!

I did. Just to get the rocker geometry to come out right.

If you mill the heads you need longer push rods.

Probably not.... that is on the margin of being OK, and you will just have to check the lifter pre-load at the end and see what it is.
???? Not seeing how that changes rocker geometry unless:

Valve length changes, or

Rocker shaft position changes

But I may be missing something else.

I think that may have been the case. I didn't measure the new valves and I bet they were different length than the originals. The lifters were not the same as the original dumbells either. The rockers were way off and I bought longer pushrods and had to shim the shafts as well. Tolerance stacking!
