I am planning on building anouther 350 engine soon and was wondering which set of heads would benifit me the most and if I can put bigger valves in them, they are cast numbers 14022601, 3998993, 14102187, and 332882.
If none of these are good what is a good aftermarket head to use and are reasonably priced, the cam I'm wanting to run is a Magnum 292H from comp cams.
