F20C1 head swap on a K20A2 block

[MJ23FE]

First question thats just an extra before my main question:
I was reading through the April/May 2002 issue of Honda Tuning an article about the K-series engine. It was called All In The Family. Well in it they talked about how if you tried bolting on the K20A2 (type-s) head onto the K24A1 (crv) block that you would run into problems with piston speed, and that you would need to seriously build up the bottom end. Could that work if properly setup with the right parts and good tuning?
Here is my real reason for writing this thread.
If you had a K20A2 (type-s) block and bolted on an F20C1 (S2000) head on to it how would much performance in terms of hp and torque would it gain? The S2000 stock has 240hp & 153 lb-ft tq., and the RSX-S has 200hp & 141 lb-ft tq. in stock form. I read in the same article that the head gasket in both the K20A2 & F20C1 are the same, and this guy named Paulus Lee from AEBS said in the article that the headd should bolt straight on from the F20C1 to K20A2. What do you guys think??? Would that sort of Frank swap be worth on anyone's Type-S??? Is it worth downgrading from i-VTEC to the classic VTEC? Come to think of it, you might be able to brew a turbo setup alot easier for the car since i-VTEC and its new fuel system would be taken out of the picture. Or am i just a complete moron and would changing i-VTEC to VTEC play no part in the way the fuel is delivered? Anyone out there willing to touch this subject would be greatly appreciated! Thank you!
