what would be your diagnosis?????

on my 340 I cut the head gasket side of the J heads .010" and decked the block .010" - did NOT cut intake side of heads and no cutting on the old LD340 intake. the cutting was done just to clean things up. I like my intake gaskets squished tight, 1213hp fel pro printoseal. the intake was a tight squeeze down, had my 275 pound friend stand on it when I bolted it on-15 years and no leaks
