Cut heads .025 thousandths...do I need different pushrods?

Put it all together as a mock up and see what you get.

Since milling the heads lowered the rockers, you can gain most of that back with the shims under the pedestals. I have a set of milled GT 40's, and finally checked stuff and its run fine for 8 years without the shims.

The Crane Cams rocker arm shim kit should get you there with the pushrods you have.

I would check piston to valve clearance while in there.

I gotcha, but I got stud mount rockers...
