PRW rocker arms

Does anybody know whether the prw #0246003 rocker arm will clear a460 head 1.640 springs?
Thanks

I have no idea about whether it will clear or not. Never heard of that part.

However, let me add that another BIG factor that determines whether it clears the spring or not, is how far up on the rocker stud you let it ride. What we're seeing is that some of the older heads that are out there, such as an EX 514 with old ARP # 1701 rocker studs (1.900" tall) have too short of a rocker stud. The problem occurs when a guy gets his rocker arm "up" on the stud where it wants to be for good rocker arm geometry, then there are very few threads left for his polylock engagement. The current TFS heads have a longer or taller rocker stud than that old ARP 1701 part number, in order to help solve that problem.

I have a set and I do know they clear my a429s really nicely, they have a notch in the rocker trunion and that is nice.They are some nice looking rockers...

IDK, but this is a PRW aluminum rocker used with a mild solid roller and Isky 9365's.

Never use any Chinese part with a bearing in it.

If you are looking to buy I have a set that would not work right with my package, I am running Miller 1.8s now. They look almost the same as my Comp Stainless ones.

Thay don't seem to be a bad part at all, everyting looks good and sturdy that is why I bought them. A friend also uses them on his A460 engine and I was able to fondle them before I purchased this set for myself. BTW, my buddies has been using his for 3 season of drag racing and please use on the river in a Bad Ass jet boat.
