Can it be done? 20V head on a 2.3 NG?

[JShadzi at aol.com]

The 10v comb. chamber is 29cc, the 20v is about 38cc, the resulting drop in compression is more like 8:1, not 7:1.  Yes, the head fits perfectly, you can even use the stock NG head gasket, the real issue is intake/exh. configuration and proper fueling.
