Did the exhaust manifolds change as well? I got a manifold from a lister
last year to replace my crappy 4-1 header, it had the combined center
exhaust port. Are they all like that or did Triumph update them eventually?
If they did, is it a problem to use the earlier manifold on a later engine?
MKIII engine, in my case.
BTW - any idea what actual displacement a .030 overbore of a 1296 results in?

The Mk1 and 2 models share a common head with a siamese intake port for
>the two center cylinders. All other heads have 8 distinct ports (4
>intake, 4 exhaust).
