What is the difference on a Profiler-https://www.profilerperformance.com/176-sbc-23-degree-heads.html VS a .ATK High Performance Aluminum Cylinder Heads for Small Block Chevrolet SBC64195
Are these the same heads? I see flow #'s are different on the exhaust but they look similar. Would the standard valve spring package work. I have the the cam in my sig. installed now but wouldn't be opposed to bigger.
