Does modifying a manifold for use with Jay's adapter prevent the use of the manifold on a 351C engine?  I want to sell a Offenhauser tunnel ram that has been modified but I don't want mislead the buyer.

Bob, there is a 351C gasket available that includes a valley tray.  It contains the complete valley cover and end seals.  People have used that gasket with intakes modified for my adapter to make them work on a 351C - Jay
