How much did you fly cut on your piston above ^^^^
I have -2cc diamond pistons, does that mean 2cc total per piston? or 2cc for each valve relief, or 1cc each relief?
I was thinking of milling my 243 heads .030 and using a .040 cometic gasket and running a ms3 or custom cam..
what kind of power would I be leaving on the table if I didnt mill the heads and left them at the stock 64cc and ran the cometic .040 gasket which would put me at 10.6:1 compression or mill and get up to 11.5:1 compression..
what would be the power diff?

Yeah see what u mean about valve getting into the edge of where its dished. What cc valve relief would i need going with a set of flat top 30 over pistons if i milled 20 thousands off of a set of 243243's

I'm pretty sure the typical 2cc would be fine. I'm no engine builder though (just my own engine, lol). So I'd ask someone with more knowledge than me.

any change in there will change compression... flycutting pistons isnt the easiest thing to do and you can easily go too deep and break thru... I'd suggest paying a shop to do your cam install and flycutting...
