My guess based on my pinto's of past,
1 110-115
2 120
3 150
It all depends on who does the head, the mad professor is the best and one I have used in the past, but I always went for 2.1(v6 pistons) amkes a remarkable difference as does balancing/lightening allowing it to rev a lot more freely.
I have had a 1700 x flow AUTO(mk2) that absolutely slaughtered my mates 2.0i sierra ghia, next I had a 2.1 pinto auto that was much faster than my xr4i, and this was on a 32/36 carb, though I had a 40DFI to fit, but sold it to someone with a reliantit was brand new never been fitted.
If you are going sidedraughts you want totally different headwork than you would at step 1 or 2.
