Knock, Knock, who's there? Broken rocker stud. So just how far down should the polylock go on the threads of the stud? I had just about 5/16 of an inch. Using stock length pushrods, standard l98 valves, stock roller lifters, lt4 valve springs, 1.6:1 jegs roller rockers which puts valve lift at .512 with the cam I'm using. Set preload to pushrod snug and 3/4 turn plus 1/4 turn with lock screw. 900 miles on the rebuild.

Any Ideas??

Fully engage, get longer studs.

I had a similar amount of engagement with the stock studs. I bought the longer version from ARP, perfect fit now.
Sorry, don't recall the part number.
