hole in my head

Cudafever - The receipt I have is from Fox Engine Service in Jacksonville, Fl. It reads " Angle mill heads & correct bolt holes etc., 3 angle on seats; back cut valves, exhaust guides" totaled $312. I bought the motor on Ebay from a guy in Florida. He said he had cancer and needed to sell. He since passed. He seemed pretty proud of this engine put together by a guy named Jim Blackshear (NHRA Hall of Fame?) I talked to both of them and they seemed like straight shooters.

First time I got on it the engine blew a frost plug and got hot. That's why I have pictures of the mill work :-)

Was I taken "Hook line and sinker"?

I really hope the intake (RPM Airgap) wasn't milled to accommodate.
