Straight 6 swap?

i understand about the cost of the head, it isnt a high volume head like small block chevy or ford heads are. and since you already have the crossflow head, then use it. it is a good head. that said most people dont have the wherewithal, or the needed skills to adapt the crossflow head to the US block, and the heads are getting harder to find. try finding an aussie 250 2v head which would be a direct bolt on to the US block, and would accept the intake and exhaust that mike sells. anther alternative is the argentine head, but you need the intake and exhaust manifolds that go with the head as they will not interchange with the US/aussie heads.
be sure to check out the tech articles on adapting the crossflow head to the US block if you havent already. jack(mustangsix) has already done the conversion and it does run quite well, be even he says he doubts he would do it again. and remember that you will have to source the cam from australia because no one here in the US sells crossflow cams.
