piston/cylinder head question

You sound like me in my late teen early 20's. 69 Dart GTS 340, 4 speed, 750dp, ld340, headers, 4.10 suregrip, sig erson cam 300dur/500lift,TRW pop up's. The only clutch I could keep in it was a DC race clutch and pressure plate, SS springs and Sox & Martin pinion snubber. Ran like a stripped a## ape. Man I wish I had that car back. A little trip down memory lane.
