Cosworth, much cheaper and really good. Better than that Cometic crap. Check out Hijacker's Cosworth HG thread here in the SR forum and the links to eric's blog he put up.

Bam! Saved you the trouble of searching for it :D

I vote Cosworth was well. The gasket has held very well, and given all the data I received from Eric on it as well as some of the emails we had going on about the company and the products being put out, I have full confidence in Cosworth (not that I didn't before, they are one of the winningest names in racing history)

i was also lookin at them and because of there extensive experience in f1 i think that speaks for itself, now afew more head questions, i was looking into 1mm bigger valves, would this be compatibale with the stock valve spring and retainers and keepers or would i have to upgrade those too?? and then with the Headgasket, is the stock bore size 87mm, and what is stock thickness?? i would like to keep my stock compression ratio, unless anyone has any other opinions on that
