Early/late G60 inlet manifold differences?

[JMC 0]

There were 2 different G60 inlet manifolds, and I was wondering whether these are completely interchangable, and what the differences are between them?

was there?

i didnt know that, learn summat new every day, if so i reckon they would be the same assuming the other one was a rallye specific one?

Slightly bigger ports on the later one I think - the head changed at the same time roughly and so did the gaskets.

Aha, off hand do you know which was which (which code was earlier and which later), as I get the feeling mine has been changed at some point. I presume therefore that you need the right gaskets for the right manifold too then...
