I assume you are talking cast heads? If so, yes, you can run 4V extractors on a 2V head ect. On AFD 2V and 4V, they are identical.

I'm considering the 3V's from CHI but just not sure if the turbo manifolds I've alreadt built for the iron 2V's will fit, I can change the flange plate easy enough but not if the port layout is different.

I'm sure john can sort me out tommorow.

As potty said they'll fit. My 218cc's basically have a 4V exhaust port. I've made 2V extractors fit. Doesn't leave much metal to seal but it does seal.
