ALL the heads will inner change 230,250,292 all being semi close to in CCs the 194 Has the smallest CCs. On a Stock bore 194 The other heads can drop the compression. Was as the 194 put On the other block can Up the compression But even More so If a Flat top piston is used which get you into the 10-1 range , BUT a 292 with a flat top can PUT you at 12-1 or over.
As for the 230 in 64 it was not in The ChevyII at least Not in either chevyII/Nova book I have it did not come into play till 65
But I do believe it was in the 64SS chevelles at that time They also came with many Chrome goodies as well.
God doesn't like ugly.
