you should just send the head  to Carl/ Iceracer or whoever on here to get oringed, you will curse that head gasket for ever.  They added a stud for a reason, plus those cometic  head gaskets are not cheap

I plan on having this done after the riding season but I really need to get this thing sealed up correctly before this weekend! lol I'm headed out to Glamis and dont want to be stuck on the 450 when I race a Renegade 1000
