Head Gasket Leak - What Did I Do Wrong

[RonLey]

Finished rebuilding my 1928 Roadster engine. I have a copper gasket and I sprayed it down twice with Perma Tex Copper Gasket Spray. Over the next week I tweeked the nuts to 55# several times.

I filled the radiator with antifreeze and got ready to start the engine. I cranked it by hand a number of times without the sparkplugs. I notices that antifreeze was coming up through the nut on the first center stud so pulled it and put on so sealant.

As a fluke I started to time it and put my finger down the #4 sparkplug and felt moisture. I pulled the head and the #4 cylinder had antifreeze in it. I pulled the head and the gasket came right off. It didn't stick at all. I have Perma Tex Copper Gasket Spray residue on all of the block and head indicating what should be a good seal.

I have taken off the side cover to check it and will now pull the oil pan and clean it out.

I am at a loss. I am going to check the deck and head again. I thought the gasket spray would be more sticky. Is it possible that I should have sprayed a heavier coat on it?

Ideas??

Thanks
