Shane an alloy log type manifold is more effective than it looks I use the 30degree down draught SU manifold inverted as it seems to work better as a semi up draught. Originally it was fitted with an HS2 SU but as the engine was developed it was bored out to take an H4 SU it's a standard JB manifold with ports matched and polished. Terry.
