the heads are from 1978 and were also completely rebuilt. i believe 1978 would be screw in instead of press fit, correct? i didn't think the threaded in studs had an issue with pulling out.i did pull the rocker off and look at the stud, it wasn't loose but i didn't measure it either. i will double check tomorrow, thanks for the suggestion.
