Slant 6 troubleshoot help!

Thank you!
Don't replace intake gasket until you do the valves and vacuum/compression test. I had one bone stock from 1967 and the gasket was still good...darn lash was still spot on too. 1st start, No fuel feed so it died. This one had no exhaust either, just a head pipe.

okay thank you. I’ll do all the tests first and make sure everything is running as it should and go from there!
