Valve train advice

I am doing some engine upgrades and need to get new rockers for my 113 L98 heads.

I am looking at comp steel self-aligning roller tip rockers.

or do I switch to non-self aligning and add guide plates for full rollers for only a few bucks more? Is there more to it for using these? Pretty sure my heads have studs already. There are currently no guide plates on them.

Re: Valve train advice

The heads would probably require machining for guide plates. Comp S-A rollers should work for a street application.

Re: Valve train advice

From what ive read the heads came with guides for assembly only. So i dont think they will need machining for guide plates. I am prob gonna go with the Comp S-A rollars. Was just looking for opinions.

Thanks again as always!!
