going o-ring or fire ring is dependent on power level, what you plan to do with the truck and the abuse the engine will see. some guys need it at 1000hp, others get away till 1300hp.

Wagler sent me some O-Rings that are 0.070' thick and was told to cut 0.063', only leaving 0.007" of protrusion. Does this sound correct? What size wire is everyone running and how deep are you cutting?
I am just looking to O-Ring the head...
