Shaft mounted rockers

I realize these are way overkill from an operational standpoint for what I'm planning but wouldn't this get rid of the whole narrow/wide, self aligning/non S.A., guide plate nonsense? I'm guessing I'd have to go to perimeter bolt valve covers but would I need tall ones?

Re: Shaft mounted rockers

The only time you really need tall valve covers is if you're using a stud girdle or have longer than stock, valves and springs. The majority of stud or shaft mount rockers will fit under regular valve covers even if there's just some minor clearancing required.

Re: Shaft mounted rockers

Thanks. What about the guide plate/self aligning issue?

No idea. I don't deal with SBC parts.

Re: Shaft mounted rockers

nope. With shaft rockers no need for self alighning or guide plates. The rockers mount on the base which mounts to the head. No movement side to side.

Re: Shaft mounted rockers

Skeptic that I am, I would have to be somewhat suspicious of the quality of this setup!!!!! About 1/3 the cost of a Jesel shaft system, is the quality about 1/3 of the good stuff, too???? Definitely an import piece.... For me, I'd have to do the see, feel, touch thing on them before spending any money.... I guess if I had enough engine to justify a shaft system, I'd be for going with a known product rather then something that could be nothing more then a cheap knockoff.......

Re: Shaft mounted rockers

Yeah for that price it's made in China junk, the hardware would probably never hold adjustment and lead to failure.

Re: Shaft mounted rockers

The only good quality shaft rocker system is Jesel or T&D. That SBC set is good for a typical street engine but I wouldn't trust it on any kind of real performance engine.

You would actually be better off buying some Comp Pro Magnum rockers.
