9 to 1 Piston for EQ 62cc Head

I think we understand what you have. No you don't need a lot more dish to get down to 9:1.

My post #8 was to explain how to modify the KB232's for use with the 62 cc heads to have the quench that you want and how much to take out of the chamber area to get to 9:1. The elevated pad can be used as is or machined as needed. At .050" tall, it isn't actually tall enough to give you quench with the open chamber heads, unless you have milled the head or decked the block. With stock LA deck and unmilled X or J heads, and a .039" head gasket, that pad will give a quench gap of maybe .090 to .100".

BTW.... IS you block decked at all? Is it an LA block or Magnum block? That changes the equation; I've been assuming an LA block.

I like your car!
