If I had to do it I would use 3.3 heads, have them stuffed with slightly larger Ferrara valves, Welded and ported to 3.2, and twin plugged. I have seen a set of 3.2 heads fail (crack) in the area of the secondary spark plug taps. I guess the stronger alloy isnt B.S like I used to think, just had to see it for my self.
