Need Help! Headgasket compatibility 2.1block-2.3head??

[Stpndsmnn at aol.com]

Is there a headgasket that will make the 2.3 (NF) head compatible with a 2.1
(KH) bottom end??   I have this combo bolted together right now and a small
part of the water port for the upper radiator outlet is exposed.  It looks
like that port is wider in the head than it is in the block... so where it
should hit gasket it just hits empty space.  Would an NF or other head gasket
cure that or am I trying to do the impossible???
