I bought a pair of 1399# non emission AFR 165 heads off a guy locally and need to know the stud size for the rockers and also bolt size of the heads. AFR's website is currently down.. again.
I have Comp Cams pro magnum roller rockers which have 7/16" nuts for the rockers and the rocker nuts are larger than the studs. Is there any studs I can purchase that will screw into the heads and also accommodate the 7/16 rockers? :headscratch:
Lastly, I heard the non emission heads use a 1/2" bolt size where as the others use 7/16, Is this true? If so, what bolts am I looking for to attach to a 302 block? :headscratch:
Thanks guys, I tried searching but didn't find specifically what I was looking for.
