Default 6.0L heads with 5.7L gaskets

If I have 6.0L heads can I use the 5.7L head gaskets or do I have to use 6.0 head gaskets?

Thanks

Need to use the 6.0L gasket or a little bigger (approx. 4.10 bore) if you are gonna spray nitrous since you could possibly have problems with the gasket not sealing properly.

Are the heads milled any?

If the gasket didn't seal properly, why would the problem be limited to nitrous only?

A friend of mine has the same heads as me and was spraying a 100 dry shot. When spraying, he was getting bubbles in the coolant overflow tank. It was discovered he needed to use a larger bore gasket than 4.00 to prevent lifting of the head.

akw408-this applies to all blown/sprayed applications more than n/a due to the higher actual cylinder pressure.

Ohhh, good to know. I actually have 6.0L heads with 5.7L gaskets right now, but haven't noticed anything yet. I'll keep an eye out for it and swap if I see anything.

What is the PN on the 6.0L gaskets?
