I have Cometic gaskets on my car now - well I ended up having to replace all the pistons (from forged Manley's to Mahle's) - so I had one cylinder head bolted on with Cometic gasket - now I am in need of another one, and the main problem is this: Cometic is behind about 3-4 WEEKS with orders and my car has been MIA since the middle of MAY. So obviously I'm frustrated, however Summit Racing has Fel-Pro head gaskets in stock and ready to go - the cost for 2 Fel-Pro gaskets is less than the cost for one Cometic - so I am wondering about the quality of the Fel-Pro gaskets. I will be spinning a 16# pulley so it's gotta be able to handle a considerable amount of boost. Anyone have experience with them?
