I run those pictured dishes at .010 above deck unless the bore is larger than 4.355. I also tend to have the chamber sizes reduced by milling. You want the distance tight as you can. Closer to .030 the better. You will also want to choose the cam carefully as too small will give you more grief than too large will when building for quench.



why unless the bore is larger than 4.355 , and what would you do then ?

The only thing I have to go by for a quench pad is the KB piston and they don't run it out to the edge of the piston , at least the pictures I have seen of them they do not ?? but this of course is ASSuMEing that the KB pad is correct ... but now that I think of it their piston specs for big block mopar engine is less than optimum
