cylinder head rebuild

.100 off the heads - that boosts compression - what do i end up with in doing this - what about .030 or .040 or .050 - whats the factors in this - trying to understand what are the limitations or to be careful with this machine work - i get quick answers but not the whole arena -

The compression on slants blueprints into the high 7s. Even though they are rated higher. LISTEN to what we are telling you. Knock .100 off. If you end up with a true 9:1, it will be a miracle.
