In NSW you must comply with the pollution requirements off the engine or the car, whichever is the newest. So if you use a HX or HZ block you must comply with the requirements of 1976-1979 ie ADR27A. Without a lot of expensive testing you cannot achieve this with the top end of an EFI engine on an ADR27A 308. However if you use the whole EFI engine it is easy, other than having to fit cats and a ULP filler neck. Earlier cars ie HQ and HJ are easy as you can use whatever carby you like on these, just need a canister on 1975 on HJ's, thus you can simply stick the EFI top end on the earlier block and you are sweet.
This is all letter of the law stuff though, in most cases you'll get away with stuff as Buck says. What Buck is sayng is fine for early WB's as these are ADR27A only, but the later cars are ADR27B and C and further so you can't legally do it, not easily anyway.

Here is anothr bue 308 with 4spd pattern. It says it has HQ heads, but manifold is pollution so not sure what is going on. Has HEI dizzy too. If it is a blue block with HQ heads you can still leave it as is, just have to get a KC castings inlet and bolt on, or get a blue motor one and drill 2 x holes for the middle bolts on the heads.
