longone, didn't know there was a .019 gasket, who supplies those?[/QUOTE]

The cometic gaskets in copper can be had as thin as .005, check with
FBO. This brings up another issue with the head gaskets available for small blocks. Unless you have a set made for your engine with it`s specific bore,then you`re probably getting the "one size fits all" gasket which is made to accomodate a 340 bored .060 over. There`s a lot to gain by finding/getting a head gasket made to fit the exact bore you have.
