Well Vegas bud..
Your timing is pretty good for this to happen..
I am wrestling with an OD issue right now, but I have a 365 day season..ahem.

I HOPE it's only the head gasket...No water in the oil?
Others WAAY smarter than me will come along and get ya heading in the right direction

Pictures of tools are cool, but won't solve your problem.
Can you post some pictures of the head gasket surface of the head and the block? That would help. Tight quarters is just part of the job.

I don't see them either, make sure you get a good shot of the bottom of the cylinder head as well.

Not sure why you deleted all your posts here, but you asked why you had such low compression between two cylinders (around 30 psi as I recall) you said you posted pictures, but all you had was the valve cover, the rocker arms and some tools. Then you said you updated the pictures, I looked for them, couldn't find them. Then your post that you really didn't post them.
Then you delete things and say you were trying to help others??????? Sorry, but that wasn't helping anyone.
