No part numbers on rockers, but I did find "1.7" stamped into the sides. I know they are not copycats because the steel rocker beam (for lack of a better term) is stamped "Jesel". Looks like you are right about this. I appreciate the help and relief. Now I need to figure out if I want to get offset lifters first, or just run what I got and get the right pushrods. I am guessing that the straighter the pushrod, the less valvetrain problems you will have.
