head gasket question
I am going to put together a 547 in the next couple of days and I have a used set of Cometic head gaskets and wonder if I should spray a light coat of copper coat on the gasket or use as is? The block surface has been machined and the P51heads are very fresh and the pistons are flat tops so it should have 14 to 1 as I think the heads are 73cc if I am not mistaken. These heads have been worked over and the intakes and exhausts flow VERY VERY good.

If it's good enough to reuse, you should install it the same way you did the first time.... Clean & Dry. But I would suggest a new set of gaskets.

I've reused them with copper coat and with nothing but a good cleaning. I'll probably never spray copper coat again.

Re: head gasket question
Why would you re-use a head gasket? Am I missing something? Are the Cometic gaskets intended to be used multiple times?

I’ve reused them as many as 3 times. I’ve used copper coat but have had good luck just painting them with rustoleum grill paint

Re: head gasket question
A lot will usually depend upon whether they are being used with a pressurized cooling system or not.
