I certainly agree, with respect to the "3.6," that I'd much rather have a nice broad torque curve than a peaky high HP motor. If this is achievable with the 3.2 heads, fantastic, though as far as I know, the X51 heads are a good bit different than standard 3.6 heads, which are already quite different from 3.2 heads.
I'll be very interested to hear what you find once you have a look at 3.6 X51 heads on the flow bench.
