roller rocker

Are you having an issue with them. My engine is back together and running good. So far So Good.

Thats great. Glad to hear it turned out well. No issue still trying to figure if this is the rocker I want to use. You know anyone who has used them.

I haven't tried the Scorpions yet. No one seems to know where they are made but by the same token, neither the Ford Racing/Motorsport versions either.

Those I am presently running. Ran Harland Sharps too.

The only question in my mind with the bolt downs is the 5/16" mounting bolts. This is even "refered" too in the manufacturers instructions.

They tell you not to excede a certain valve spring value.

I used a set of the Ford bolt-ons on a 302 and had no issues with them. That was an everyday use truck.

Make sure the threads on your heads are in perfect condition, each and everyone of them.
If they aren't then go a different route.

I'm running the Scorpion SCP1023 Race Series Roller Rockers in my 383 stroker Cleveland.

And, Scorpion rocker arms are Made in the USA. If I recall correctly, Dan Jones recommended them to me as being a quality rocker arm in the lower price bracket ($300) before jumping up to a $500 set of Crane Gold Race roller rockers.

I just put a set in the garbage with about 1ooo miles on them I replaced them with a set of Ford Racing rockers. The roller tips was already starting to get gritty on 40% of them. That being said, they are the best cheap rockers you can get IMHO

Yella Terra YT6015. Billet aluminum. Made in Australia, not China. Tim Meyer Inc is one possible US dealer for Yella Terra parts. There are others. The rockers are not cheap, but they are made to a standard commensurate with their price.

The latest in thing is that a product is "assembled in the USA of 'worldwide components' ".

Exactly how roller tips wear out is beyond me. I would be more concerned with the push rod cups. Those are hardened steel pressed into aluminum which may or may not have been hardened to T6?

The entire point is that they roll on the tips, not drag across them. That virtually eliminates wear.
