Pauly, made manifold myself from old su flanges. Then using 40mm aluminium pipe on spare head set up angles and tacked it in place. Pipe cost $40 for 2mtrs, mite get one custom made with all the smooth bends but this will do for now.
Neuby, Each runner is 125mm long and go up on a 30deg upward angle to keep fuel bowls horizontal. Extractors are heat wrapped, but will definately make up a heat sheild soon.
Zeddophile, wow nice! I was thinking of tbs also. Each carb is individual with the same linkages as yours from the sounds of it, but mine have 2 rods that run through each carb top and bottom, once i removed those they all separated then i just got longer rods.
