With closed chamber aluminum heads it will have proper quench.

That’s how I’d build it.


Same. I think that this is exactly why Eddy built this 84cc head. Common 2.06" something piston at zero deck and 0.040 gasket.....perfect CR with quench. Don't put too small of a cam in it.

OP - have Dwayne spec you a cam too.
