Dome vs Flat top.. I am debating about what combo to use for my next 2 engine builds. I can either heavily mill the heads / use flat tops or mill the heads .030 / use a dome piston. Any input from you serious engine guys?

I need to set this new motor up with 12-12.5:1. I can go with a 8 - 10cc dome and a .030 mill with a thin gasket. If I did it all in the head it would be a .060+ mill?

IF you mill the heads you will compromise your PV clearance. If you take it out of the pistons and the if you need the exster point of CR then u can take it out of the heads. If you already took a .030 -.040 of the heads and you need more but your PV is to close you have screwed your self.

If I get dome pistons they are going to have reliefs for the valves. I guess I am more worried about flame speed and if a dome piston will hurt performance due to a slower flame speed.

Any time you add a peak to a combustion chamber you are going to add a hotspot. The Ideal condition would be a totally flat piston with a small combustion chamber; in real life conditions that is hard to do. I would compromise with the smallest cc chamber I could get then calculate what piston cc I would need to get the desired compression ratio.

I'd talk with someone that has some experience with milling the AFR 205's.
What bore are you thinking?
