Just received a new set of aluminum heads for my 340 build, Promaxx 171/65cc heads. Never ran aluminum heads. Anyone have any recommendations for head gasket materials to use or ones to avoid?

Appreciate any thoughts.


Thanks

Alot of guys run Cometic when using aluminum heads. They also have a wide range of thicknesses
to dial in your compression ratio.

Cometic or Fel-Pro HP head gaskets with a "Pre-Flattened" SS Wire. Also, use ARP head bolts or studs so you don't destroy the tops of the head bolt holes.

I'm not a small block guy, but I'd go with the Fel Pro wire ring number. Small blocks are known to have head gasket issues.
