rocker arm question

I am wanting to get som full roller rockers for my SBC 400 build, But I'm not sure what kind I need. I know with STD stock rockers they must be self aligning(vortec heads), does this apply with the rollers too??

how are the summit brand full rollers, crane gold, erson??

My Harland Sharps, 1.6:1, had them a long time.

Get real close.

If your setup reqiures self aligning rockers stock it will also apply to the rollers as well.
Check out the pushrod hole in the above pic I posted, see how tight it is,
the pushrod is held in place ?
That aligns the rocker, self aligners will have a "grooved" tip.
Like these.


Proform example.

BTW you canīt use self aligners and pushrod guideplates or heads like mine which guide the pushrod.

I just bought the summit aluminum 1.6 full rollers non anodized. After asking the same question you did and many responses from the members I can say I'm completely satisfied with the summit brand. They are much beefier than the ones I had(overseas rollers) they were relieved to clear 1.55 springs and all around were better built than the old ones. They also came with adjusting nuts. The Harland sharps pictured above look way thinner than the summits. I'm not saying they are better than the Sharps but alot more material. The cool thing about my purchase was Summit sent a 50.00 off coupon if I spent 200 so by the time I got the other items plus the rockers it only cost me 100, instead of 150 for 1.6 full aluminum rollers. Good Luck

Thanks for the follow up. Post it in that thread so everyone who references it in the future knows what the result was. Did you find out for sure who makes them?

A tech at summit finally was very helpful and said they were from crane and he had even used the rocker arms on his personal projects which were roller cams with 600 plus lift. Again I would love the comp pro magnums but the summit brand I bought I'll take any day of the week.
