These 'pioneers' were the ones that gave Firerings a bad name. I personally believe that they are a notch above o-rings.... but either is good, if the head is decked and the groove is cut properly! JMO

I agree whether or not I will get fire rings is yet to be seen... fire ring is a complete ring where an o ring has a slight gap that is left up to the machinist... also a fire ring completely isolates the combustion chamber from the hg... where as the oring is pressed into the hg correct?

That was my understanding from a conversation with Van Haisley, three yrs ago... but it was mostly over my head back then!
I do know the Firering gasket still has the metal sealing ring around the piston but is recessed from the lip of the cylinder more than standard gasket.

O-ringing is less invasive. I think .015" is all that it needs? Don’t quote me on that. And Fireringing is .040". You can just do the head, bock and head or just block. The o-ring is built into the gasket........honestly.....IM going to do studs and a MLS gasket when time comes....i "MIGHT" o-ring just for S&G's and i now have access to a rig to do it myself if keith will let me! haha!

Fade.....careful what you wish for! HAHA...i cant say enough about this group myself.....great bunch i still like to call my Texas DTR family!

Standard Firerings come .105, .118, .125!
Haisley can make any size requested.

OK, thanks for the info RJ. Im curious now who I could go to with my own head to avoid that problem, if I ever got to that level of performance.

Good luck finding the right shop/people to do yours B.
