Comp XE268H cam and lifters

Yea, I was looking at them and planned on doing them.

I saw on comps sight they say you need an adjustable valvetrain also. Is that true?

No. Just run the appropriate springs, retainers and locks. I run the HE268 under stock rockers. The only issue that might be of concern is the old rockers might stress with the added spring pressure.
