Once I put a worm clamp on there, I was able to properly seal it.

That sucks about the head gasket.

Maybe now it's time consider performance heads? Since you have to do the one side, may as well do both and get some performance if you have the money?

I'm assuming you'll need to get a dyno tune after these as well.
