1-What is the dish diameter on them, if anyone knows?
2-Has anyone fully dished them, removing the D-shape from them?
I know that some people have dished them to 0.195" (I think) to get more dish vol. (read that it's 26, but more like 24-24.5 according to my calcs) but I'm curious if anyone has done anything other than just dished them to 0.195". I talked to Fed. Mogul/SP and they said as long as you maintain 0.25" min. thickness on the top of the piston you should have no issues.

Re: Couple Questions on 677 Pistons
if you remove the D shape you'll effectively eliminate any quench benefit.
