I understand what you say about the heads now. I have seen them before. I take it that there is another throttle body as well as those individual port flaps? I can't be too sure but I think Karl on here who is an engine designer by trade has studied the heads but I can't recall the outcome of his findings.

An engine builder over here imports them or at least has a source who imports them but I am not sure if they import the head a swell. I think it was just a short motor they imported.

With forced induction though, the capacity isn't the restriction on power as the turbo compensates for the lack of capacity. The advantage of a larger capacity engine is the ability to spool up a larger turbo lower down in the rev range due to the larger gas displacement.

I personally have stuck with the 1600 CVH as they rev a little better than the longer stroke engines, producing more power higher up the rev range when the other engines start to die off. It helps with traction with the cars only being front wheel drive.

A few people over here have managed to fit the MTX75 5 speed box into our European Escorts but I don't know about the US Escort or the 6 speed box. We have the luxury of being able to fit the Quaife ATB diffs in our origional boxes which is what I have done. The car now drags you round corners, makes it a lot more interesting to drive.
