If you’re planning on using a closed chamber head and zero deck ...... you’ll either need to get the heads down near 55cc’s, or use a piston with a net dome volume of around 0cc’s(with 60cc heads).

Open chamber heads will allow positive deck heights...... but then you’ll have to balance the chamber volume, gasket thickness, quench pad area depth, valve pocket volume, etc.

The easy button is a 4” crank.
