Flycutting cast pistons.

I don't know that that is the deck height yet. But I hear what you're saying. What is the max safe cut that a 318 block could safely take in your opinion?
The chamber volume will also dictate the feasibility of running zero deck too. I do want nice stout static compression, but I also don't want a knock happy pig on pump gas. (I've driven a family members 340 which hates modern fuels with a vengeance)
However I seem to read in threads time and time again that the 318 was afflicted with some dismally low CRs from new.
