Default How much can I shave heads?

How much can the stock heads be shaved to raise compression ratio without getting new pushrods or adjustable rockers? My cam lift at .500 is .569.

i would say right off without new pushrods you would want no more than 30 cut off em.
give or take a "little" but thats about it.
lifter preload becomes a issue after that much.

i have heard some taking up to 60 off em with new shorter pushrods.

I was thinking .030 would be OK. Especially since my pistons are zero deck height.

Reckless:

I know you can go up to .040 before you run into problems with manifold alignment etc. You'll just have to shim up the rockers or use shorter pushrods. But .040 is the most I've heard of without any problems.
