What are good roller rocker arms for a ls1 engine with heads cam and intake? Is stainless steel or aluminum ones better? I would like to buy them from texas speed performance

If you are using stock casting heads, I would use oem rockers with a trunion upgrade.

It has prc heads and a big cam.

I think PRCs are oem rocker friendly but if not - Yella Terras up 400 pounds of open spring pressure. With 400+ open spring pressure run Jesel Sportsman shaft rockers.

Ive seen bad things with yella terra rockers. Are comp cam roller rockers any good. Texas speed has aluminum and steel ones

Don't base your purchase on a vendors selection, base your purchase on what is available in the vast parts selection from everywhere. If you're running 400+ lbs springs you will see bad things from comp rockers as well, but inside your engine. The only failures I've seen on yella terra's are from engines that had over 400lbs. springs.

I would stay away from them. I purchased the previous design comp pro mag rocker and had one slip on me. They had a lifetime warranty, but since comp had discountinued them for a newer design they did nothing to help.
