The version 5/6 are the best but you cannot make them fit the version 3/4 cars as the inlet manifold pattern is different. The version 5/6 also have issue of cracking round the spark plugs sometimes. Between the version 3/4, I would prefer the version 3 setup but there is not much in it and would not complain if I had to use version 4 heads.
If I was going to trouble of modifying my inlet manifold to fit newer heads, no doubt I would go for the AVCS heads as they help greatly with turbo spool and outright torque/bhp.
