quench article

I'm running with .029 - .030" quench height on my 360:1
KB pistons, shaved '302'-heads. 11.3:1cr.
I haven't found the need for less timing yet, but I'm running propane which likes plenty of advance, but limited to 32° at 2800.
I've streettuned my digital timing table for well over a year and can't really find more torque in much of the lower rpm-ranges.
But maybe with the aluminium heads I will install soon, that might change again.
