Well, shoot. I don't think you need to worry about any "off boost" feel with a positive displacement. That's insta-boost.

you need a head in unknown condition that has been sitting outside for 10 years?

Shoot, I personally know 2 people that threw MP62's on their high compression motors. One 10:1 and that other 11:1. Both were putting out about 300whp. One non-intercooled. Both run GREAT!!! I'm talkin quick. One, a V6 Tiburon, is getting built up with a larger turbo (GT35 IIRC) and ran 13.2's on slicks. The other, a K24 Integra, is still running without an intercooler and as of yesterday, laid down 302 at the wheels. He pulls 13.1's-.2's on street tires.

FWIW, if you really intend to do this yourself (a very steep learing curve I imagine), the suggestion of starting with a scrap head or two is a good one. At least you'll get some idea how thick the casting is. It might be a good idea to slice it into sections on a heavy duty band saw to see what the wall thickness measures out to around the combustion chamber wall/cooling passages. I don't know how you can shade-tree the effect on chamber squish/gas flow characteristics. Racing engine builders guard these kinds of sectrets on which they've spent big dyno and flow bench dollars learning.

what kind of boost are they running? also keep in mind those are dohc motors which generally have alot more overlap than sohc (especially the 1 degree on the 944 cam)

You know where I can find info on the stock 944 cams?
