Since I have to pull one of the heads off for repair I have decided to upgrade most of the valve train. I am going to go ahead and pull both heads off and replace the stock lifters with the comp R lifters and have been flirting with the idea of replacing the rocker arms. I have read of some issues with the comp rockers not doing what they say they do and have decided to go the Jesel route for one reason only. For what I do with the car it sees sustained high RPM's for a LONG period of time, so I want to put the best rockers in I can get.

My question about the Jesels is, what other mods have to be done to get them to go on the heads. I know I will most likely need new rods and I will need a spacer for the valve cover. Is there ANYTHING else that will need to be done to get these to fit? Will I need to elongate the rod holes or any other odd ball things that most people dont mention?

Any input appreciated.

If you have the cash check out www.katechengines.com they have some sick looking valve covers instead of using the spacers.

I just clearanced the stock valve covers to make them work. No spacers.

So other than valve covers or spacers there is nothing more that I need to do except slap them on, adjust them and call it a day?

Correct.

Crane also has a set of gold race rockers for LS-1, they work well and you don't have to clearance the valve covers or anything.

watch it with rev springs, the retainers will contact the jesels. This is from personal expierance as it snapped a titanium retainer. All my jesels were eyelashed for clearance

I cant remember what springs came with my stage 2 LS6 head and X1 cam. Could this potentially be a probelm?
