Bill,

Did you say 3 different heads and still a blown head gasket.

Were the heads milled to increase compression?

When I have installed a new head gasket, I never have used any gasket sealer, 
just a light oiling never had a failure.

Where did the gasket blow, in the same spot?

Are the cylinder liners installed correctly? Is there the correct gap between 
the top of the liner and the block?

Could there be a warp in the block?

I have 87's in my 3 and 4 but with stock cam and rockers. I have never seen a 
blown head gasket in all my years with the 3 and 4 engines.

Are the heads showing damage after the gasket blows?

Maybe it is time to replace the head studs and nuts? Maybe they are stretched 
out and not allowing the even torque required. Are the correct washers being 
used?

Maybe it is time to use one of those solid copper gaskets used by the racing 
crowd?

Lots of questions but not many answers here Bill.
