Like the title says guys what is the difference between the 5/8 and the 7/16 rockers?? Is it just the collars on the Polly lockers or is it the threads on the rocker studs??? Just want to find out so I don't get the wrong bits for my cast camel hump heads!!
Cheers

hi
the 5/8 are substantially stiffer, they are also an aftermarket item on a small block chevy, not a stock camel hump head item. . . You will also find that apart from on 302 chevy heads, bow tie heads, and a very few other "special" factory engines the 7/16 screw in items are also aftermarket. . . normal fitment are push in 7/16 I would have a check as to what you have first.
best regards
