Today’s small block Ford street engine builder has it easy. Not all that long ago, the small block fan’s only choice for Ford cylinder heads was the classic 351W Ford heads swap on a 302. Today, the aftermarket lineup of Ford cylinder heads has plenty of castings from which to choose. We’d love to test ’em all, but we decided to line up as many performance small block Windsor Ford heads as we could find, as long as they were available complete for less than $1,350 for the pair.
