A pressed in rocker arm stud bolt broke on my 1965 389 head. I got it out and started looking for a few online. I can't find any press in studs anywhere. I want to drive this (new to me) beautiful car a bit before pulling the heads and having them threaded to accept screw in studs. Do any of you know who might have a few available? Mine is a bottleneck 3/8 threaded top and 7/16 press in base. Total length approx 2.042 inches. A straight 7/16 would also work. I also would like to replace a couple of push rods that dont pass the roll on the flat surface test. They are 8.625 inches long and .3 inch diameter. Any leads are appreciated.
