With a zero deck the piston should be as far away from the head as whatever the compressed thickness is of the head gasket I'm using right? So how about this plan?

(1) right and a 35-39 thou gasket will get your quench spot on (w piston rock potential measure it carefully/meticulously) (2) A true flat top at zero deck may have too high of a CR, A KB type piston that has a flat plateau to get the quench and the perimeter is lower plus the valve reliefs will most likely be a more street friendly plan unless you're building a killer w a radical cam and racing gas to keep it from pinging



KB doesn't make a quench pad piston for a 383 , which is absolutely stupid on their part.

I would also think a person would have some really loose fitting pistons to have piston rock that would contact the head using a .039 thick gasket ...
