I though this may be on interest...
I managed to pick up a couple of heads from a Tickford TE50. Apparently they’re the same as the 220kW heads, ie larger valves, ported by Perfectune/Yella Terra. Today I put them on the bench and lined them up with a standard intake manifold. It’s an interesting comparison. I’ll now use bearing blue to show where to mod the intake manifold and then break out the old CC Specialty porting gear from my bike racing days!
