Vance,
I think Billy's question was regarding the EXHAUST
manifold. The port spacing is the same on the exhaust
side.
I agree that the intake spacing is different.
The reason I did the early exhaust manifold on the
late head is due to needing an entire exhaust system
and not having any money:) I had a single pipe ANSA
system that came off my TR250(under construction).
Looks & sounds great, btw.
