What is mods are needed on centre bolt valve covers to fit full roller rockers under them?
Remove drip rails? Remove support bars? Grinding? Thanks.

If your getting the Crane Golds, I didn't have to do any modification to my covers.

I ran across an article yesterday that said something to the effect that small blocks 1990 and up are ready for roller rocker/cam setups as is with little to no modification.

Please correct me if I'm wrong because I am looking to do the same upgrade.

Hey Acceld Z, just did that mod to my valvecovers about 2-months ago, I got the info from GMHTP and I also emailed Johnny H.

Basically all you have to do is use a grinder and remove that LIP on the support straps for the CENTERBOLT guides. The GMHTP mag with Johnny's 396 build up has a good picture of it. You can also email Johnny and get the info directly. HTH's

That's correct just the lips. Don't remove the supports or the "X" braces. I did the same thing for Comp Cams Pro Magnum rollers.
