there is no such thing as DOHC 6g75, there probably never will be. there will probably never be another non-mivec 6g7x performance engine.
half and half...
correct, the 6g75 has a single cam shaft, and this is the only variant it came in, it does still have 4 valves per cylinder however so it's as good as you get.
the 6g75 MIVEC heads will fit on a 6g74 block...give or take a little adjustment
the 75' block is also missing some mount points...
the 74 block IS the way to go...you just need to chose to stuck with the standard crank, or go with a 75 crank and a little overbore to get you up to 3.7L
