Thanks to all for the thoughts. I agree I could use better parts but, again, was looking to just use what I have now. I wouldn't mind a stock build but these are the parts I have.

The other two cams I have are the MP purple 238/.474" and the Comp 292H 244/.501".

I think I will try and find the metal shim head gaskets if I can.

What are the drawbacks to advancing the cam?
