You can't just buy o-rings. Your head has to be machined for it. When I got mine, the machine shop did all the machine work and pressed the wire into the head for the o-rings. Also, there's no problem going with a stock Cummins head gasket.

Pure Diesel Power took care of all the machine work for me, including the wire. 715-254-9181 is the number for their "Tech Line." They may be able to point you in the right direction.

I wish I could give you some more help. Maybe try posting something up in the sponsors section? They might be able to get you what you need.

For all you who are curious this is what a o-ringed machined head looks like. I run mine up to 60psi with Twins and hitting 600hp at the rear. Max EGT's I can hit is 1300 on WOT.
