will know in about 2 months

The Cummins guys use what they call 'fire rings'. They are a mild steel, and they are not triangular in shape.

Does anyone know if these pyramid rings are stainless or mild steel?

P.S. There is no 'G' in Cummins

You are doing good for 18lbs on a set of l92's. veee8 on here started to lift the l92 heads just north of 15lbs on his previous motor due to the thin deck casting.

87silverbullet- i was trying to search for some of his old threads. I dont know if he was oringed and i thought he had an issue with the ls7 gastets. i forgot to add im running the ls9 head gaskets with the larger head studs cut torqued to 110ftlbs.

I heard the larger head studs don't make a difference because you are still dealing with a thin deck casting. I might go with the Mast motorsports heads since they are thicker casting and I can still use the sheetmetal intake. I keep looking at the PI heads though.

i checked the car this morning after hitting 19psi a bunch of times last night. seemed like i lost a half quart of coolant. im not sure if it was pushing water or air in the coolant system, i had drained and flushed the system yesterday, so it could of had an air bubble.

Yes they are. When I posted I was looking at those two heads at least a year ago. I just saw this thread in the engine section a couple of days ago.
