I'll take this head to a machine shop and have it verified just to be safe. I suspect that it blew because I didn't retorque.

So there also appears to be a debate about using a sealer or not on head gaskets - what say you all?

I've already said it.

Follow the directions that come with the
gasket.

Some require sealer, some don't.

Bruce,

Thanks, but the head gasket from my local Napa store didn't come with any instructions.

Is it a metal gasket or a soft gasket?
On a metal one I use sealer. Copper coat usually.

On some soft ones too. If it is a soft gasket, what brand is it?
That may, or may not, help. If it just says NAPA it probably won't.

I never use white latex caulking on them, but I took one apart
where the previous owner had done exactly that. On a used
metal gasket no less. Not surprisingly, it didn't hold.
I don't think it would have even if he had re-torqued it.

Let me rephrase that......

Unless the instructions say do not use sealer, use it. I use spray on Copper Coat.

Agreed. You cannot go wrong using K&W Copper Coat. 1st used it back in '68 on a 292 Ford. I have used on every head gasket since including tractors and air cooled motors; never had a head gasket problem yet - knock on wood.
