Roller Rockers?

Does anyone know of anybody that sells roller rockers for the 6.2/6.5? I don't want to leave any stone unturned on my 6.5 buildup. Thanks in advance.

The only way to get anything other than stock rocker assembly will take quite a bit of effort. There was a fellow over at the page who did such a thing, but he ended up making alot of mods to the heads and valve cover IIRC.

i think a system from a dodge would work, they use those systems on all the big block mopars. but yea, you would have to heighten the valve cover and machine a lot of stuff.

might free up 10-15 HP, not much more than that though, we rev so little that it is almost not worth the gain. you loose valve train HP only in the higher revs, above 5000 rpm.

not a bad idea though, would be pretty neat to see some big roller rockers under an aluminum fabed set of valve covers.

I would buy a set. It may also help extend valve guide life. Not that that is a big issue though.

It would be nice to have a higher quality set of rockers along w/cast alluminum valve covers. If the valve covers didn't crack from the vibration they would sure seal alot better than the OEM pressed steal variety. A set of custom injection lines would have to be fabbed up to provide clearance for a taller valve cover.

I wondered if taking my valve covers in for some really heavy chrome plating and making a set of thick hold down tabs would help in the flimsy valve cover department. I do not care how they look - just beef them up a bit.
