So in the US did the intake ports start close together and then get wider
apart? Or did they start wider and then get narrower?
The reason that I want to know is this: The head on my car has intake ports
that are farther apart than the manifold that I was shipped with my webers.
I ordered the weber kit for a 1972 TR6 and was shipped a manifold with
narrow intake port spacing and want to know if I was shipped the correct
part or not.
I just got off the phone with a shop in Seattle (Autosport) and they said
that they are 90% certain that the later ones are the wider of the two. I
would like to be 100% sure before I ask the place that I bought my weber kit
from pay for shipping me the correct part. That is if they will answer the
phone or return my call.
Thanks again,

Hi Bernard & Don,
Bernard - the reason that you might have not noticed a difference is that
there was not any for the PI engines! All PI heads have the same port
spacing. For some reason unknown to me, Leyland made a different head for
all North American TR6s for 1969 - 1972. After that, Leyland dropped that
head design and used the standard PI head and all TR6s.
Hope this clears it up a bit.

Hi Don,
Hmmm, narrower intake spacings... I'm not aware there are any differences
on the 2500 engines (not that I'm an expert mind). However, I thought there
may have been a difference between some of the 2000 heads and 2500. Perhaps
in the past your car received a cyl head of a GT6?
Please keep up posted on the results...
Cheers
Bernard
