The 3782461”Camel Humps” were probably the best OEM production cast-iron head made by GM from 1961-70. They’re 57.5cc chambers so you’d be looking at 10:1 or better compression ratio (unless you go to a dished piston). Intake runner volume is 170-180cc. Used on 302/327/350 engines and most have 1.94/1.50 valves. They’re fifty years old so you’d want to buy from a reputable source and definitely not “sight-unseen” from a private party. A lot of them on e-bay. – here’s a rebuilt set from a machine shop with hardened seats and Z-28 springs for $800 plus 100 bucks to ship.

Those rules sound like Wissota Super Stock rules??? We ran that class a couple years, found it easier to use this approved head rather then try to find decent used (old) heads around; Dart Wissota Approved Small Block Chevy Super Stock Head, Bare - Speedway Motors, America's Oldest Speed Shop If you're running IMCA, I heard they had a similar head available to be class legal????Yesterday is history, tomorrow is a mystery, Live for Today!
