What I'm actually looking for is a divided intake port so the TPI injectors on a Clifford intake can be fired into their respective cylinders only. My other choices are possibly more expensive like bolt in or welded in port dividers or even more expensive a Brazillian hed. Both the 292 & 230 are 3.875 bores so there shouldn't be any valve shrouding, and now that you mention it an OHC 292 would be pretty neat.
