PISTONS: Flattop or Dish for stoker....

Are your heads open chamber 340 heads or the closed chamber 360 version? Reason I ask is the closed chamber version will have a better quench and quench engines resist detonation.

I went with the KB745 step dish, closed chamber Edelbrocks (360 version) milled to 62cc, zero deck pistons, and .039" gaskets for 10.3:1 compression. Cam is custom ground hydraulic roller with 236/242 duration @ 50 and 586/540 lift. Power band will be between 2,000 and 6,000 rpm. Engine was built for pump gas and a broad torque curve.
