Default Machined 317 heads do I need diff pushrods?

Machine shop just called and he's going to have to resurface the deck on some used 317 heads I had ported. I already have 7.450 pushrods to go with the 02 z06 cam. Anyone have experience with this? I know my compression was going to drop about .5 but with say .007 cut off how much would this change that by.

Humm, why do you have shorter than 7.400 pushrods for the 02 z06 cam? Either way, .007 is just a clean up and shouldnt affect things that much. I would measure with a pushrod length checker to make sure though (in terms of using 7.400 vs 7.350).

the 02 zo6 cam has the smaller base circle, stock z06's used longer valves, I was told to run the 7.450 with the stock 241's i am currently running.
