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.

Subject: Re: Intake Port Spacing Question
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
