A full turn after the ticking stops . Really? What would be the reason. Depending on the rocker stud thread I would think that would lift the valve and give you problems. He had the rocker so tight the oil shot out from the rocker like a jet. A little splatter is expected. What is scary is he tried to drive it like that.
Also for a high school kid, a 15 second flat car is fast. Dont understand what he was upset about. A stockish 79 camaro 350 / th350 with a K camkit, is not going to cut into big block territory 13's.
