Head gasket selection question

I have a basically stock 1969 Chevy 350 (bored .040 over) with the factory Chevy flat top 350 pistons with the valve reliefs.
My question is what head gaskets should I buy such as the thickness, brand, quality etc?
I am going to put factory "186" heads back on the block.

thanks in advance,

Re: Head gasket selection question

Are you wanting to bump up the compression from stock?
Was the block decked?
A fel-pro composite .039"-.040" is stock and if you wanted to bump up compression a little I would use a .025" composite gasket. I would tell you to use a shim steel .015"-.020" to get even higher compression but I would never use one, I'd hate to have to pull the heads back off to replace a leaky gasket just to gain a fraction of a hp.

I have never had a prob with fel-pro head gaskets.

The only Mustang I'd ever own is a Fender.

Look, GM installed .020" shims in million's of our old engines.
