452 Iron heads. I adjust them cold 7/16-20 thread on the adjuster = .050 per turn. I loosen them and slowly tighten them until I feel drag on the push rod then turn them to what I am setting them at. Should I go more than one turn?




7/16-20 adjusters ??? Those would be HUGE, all adjusters I have ever seen were 1/4-28
