Thomas, I have a 39 GMC with a 228 and used a fell-pro gasket set. Its the same as the orginal and I had no leaks. I have not seen a one piece gasket, but it would be easier to install. NAPA sells good quality parts so I think it will do fine. By now you may have already installed the set, since you posted your question 14 days ago. Time passed me by, must have been sleeping at the wheel.
