Chamber size for iron head stroker

I ran these imm-prepped rhs-x-heads before, they performed very good....mid 11s in my Valiant with a moderate camshaft (242/236° @ .050").

Regarding the pistons: there is a KB356 Piston, these do have a quench pad that must be machined when using closed chamber heads like the rhs. Ask scat about the piston type, then you can machine the piston exactly to deck height (that´s what i did).
