I've tried the search, but havn't been able to determine what the best head casting number would be for a perf upgrade.
seems that there are quite a few choices, and I'm sure that each has some advantages/disadvantages. one guy on ebay says there is no diff. I can't agree. I'm sure there is a "preferred" head to use for a starting point.
If nothing else was done, other than required mods, what head(s) should one look for and why?
Never had stupid questions like this with my sb's,bb's gn's or harleys
