Re: 71 350 Rebuild advice needed - Head and Cam Suggestions
It is very difficulty to rework head for the price of new these days. The power of mass production is just difficult to make up. Especially true with pre-70/s heads without hardened seats. Even the early valve stems were soft and are likely badly worn if run on no lead fuel.
Newer heads have;
Better flow, Stellite valve stems, larger valves, hardened seats, better swirl and higher compression.
Personally I can see no reason to go back to the 70's technology unless you are restoring a truck.
