Also on the seafoam question

What is your question?

I did fill tank I forgot to add.I know all signs point to head gasket. I'm hesitant to put a gasket sealer and just bought the gasket.I don't need more problames I figured if I add sealer and it stops I figured it out but then I've got shit clogged in heads and ports.idk that seafoam has ever moved along a ticking time bomb but it sure seems to have.I'm almost positive its the head gasket.but can't hurt to get feed back.I'll be pulling head tomorrow.
