I'm building a 1990 302 roller engine to put in my 1967 mustang.I was wondering if anyone had any suggestions on valve springs and rocker arms or any other parts. I am using a motorsport e303 cam with ported,gasket matched, and oversize valves (1.85"/1.55") in gt-40P heads, and speed-pro forged pistons with reliefs. Should I use 1.6 or 1.7 rocker arms?
