Does anyone have a source for head gaskets for a 273 that doesn't have the 340 bore? TIA
 
I'm pretty sure the only place to get them now is customs from Cometics. I haven't seen any non NOS ones in decades.
 
Moper is correct. I searched for weeks when I was rebuilding mine. Cometic can make them. The 340/360 bore size will decrease compression by about a half a point. toolmanmike
 
The correct metal exhaust manifold gaskets thet include heat shields are rare too. Recon what the 4 NOS pieces are worth today ? Not that I'm trying to sell them just curious.
 
Thanks guys. I think I'm going to wind up going with Cometic, I can't find them anywhere else. I'm not concerned with the compression, more with pre-ignition and detonation.
