That is definately no problem. I built a 502 for a bracket/street driven car and used a GenVI block with early oval port, closed chamber heads. I can't recall what head gasket I used but I belive it was a GM gasket. That engine is still going. It never had any problem and has run in the 9's after it was transplanted from a street car into a racecar. I got the info for what I needed and bought some parts from one of the GM Performance parts dealers thru their catalog. Pace Chevrolet. Scoggin Dickey is another good source. Lots of good info in those catalogs..........
