Default Cometic 4.380 head gaskets

I'm looking for some .060 head gaskets, but haven't found a set in stock. Anyone know of any shops that may have some in stock?

My current head gaskets appear to be in excellent physical condition, other than slight combustion seepage (about 3/8" wide) between the center cylinders.

If I can't find new gaskets, is it possible to copper spray and reuse the old gaskets?

The block deck looks great and the heads are freshly surfaced.

What heads are you running?
If they have paired center exh ports it’s a good thing if your running head bolts to take the center two up to 100 ft lbs.

If your running Aluminium heads there deck finish needs to be near mirror like for the best gasket longevity.

High port heads. Block and heads are machined for MLS head gaskets.

I wouldn't have an issue reusing the head gaskets, if I was running NA. But this engine is going to be sprayed with a healthy shot of N2O.

I ordered .080" thick for 4.20" bore, and maybe shipps by mid-Sept. $300 for the pair.
