Thanks for the help with the gaskets.
For the headbolts - I have some 'automotive thread sealer tape' work, or should I buy something else?
I went back to autozone b/c they gave me the wrong tool to pull the bushing. I got the right tool, in addition to a slide hammer and a tool to put the new pushing in. Funny thing is, the tool that gave me to pull the bushing is too big for the new bushing. I guess it's a good thing the old one is worn out.
