Valve spring limitations vs Cam selection

And BTW, I am pretty sure on the 62 cc chambers for the EQ heads. But let's make 100% sure on that.

Dang here are the pistons I would really want to use: Icon IC742.

SCR works out to 10.3 with the Felpro 1008 head gasket with .037" nominal quench gap, or 10.0 with the standard Felpro kit gasket, PN 8553PT, and a nominal .047" quench gap. Not bad on either one, and you can bump up that cam a step or 2 and keep good DCR for the low RPM torque.

BUT, the downside is that they weight is 548 + 118 = 666 grams. So some crank balance work would be needed. I am 98% certain it can be all done externally.... start with LA 360 external parts (damper and flywheel/flexplate) and then you ought to be able to reduce those external weights to make it balance out.

Just another option....
