::Ken, I assume he is talking about the pedestal mount rockers on the 80 heads vs the positive stop rockers on the 351 heads. Do these to setups use the same length pushrods? .. The original post says he wants to use 351 heads, there fore he needs rail rockers, pivit balls and the older 302 push rods. Yes the 80 heads use fulcrums. For push rod lengths the following from book is 69-77 302 is 6.905". Late 77-78 is 6.883". Late 78 into 80 is back to the 6.905" length as well as the 255 engine. So one can not be sure without measuring per the rockers setup used.
