im rebuilding my tbi engine and i was wondering do i have to use self-aligning rocker arms? from what i understand u have to use them on the stock heads, but im not using those i have Worlds s/r torqurer heads?

 

You can just re-use your stock self-aligning rocker arms. Not sure how the World heads are setup, but your choices are to run self-aligning (S/A) rocker arms or to run Non-S/A rocker arms with guide plates and hardened pushrods. Either way is fine, S/A is easier if you already have the r-arms.

 

ok thanks for the reply, ill just order a good set of self/aligning roller rockers

 

That's prolly your cheapest option...

 

Why would anyone use non S/A's over the S/A's? Is there a benifit to this or are some heads just not capable of running them?

 

Depends on how things are set up. If you have the narrow slot pushrod guides in the heads or guide plates, you run non-SA rockers. Some TBI heads have the narrow slots with the SA rockers. Potentially you could just run non-SA rockers if the cost was less for aftermarket stuff.

EDIT: I do remember seeing someone here run non-SA rockers with the 87+ narrow slot heads and have the pushrod wear into the head. Not sure on what the circumstances where...
