Roland & Eric:
I am going to check for a manifold leak (if I can figure out how to do that)
and check the carb setup as provided in the instructions from Jim Taylor.
The shop checked for a mainifold leek and said they found none so I will do
that second. The car is running a lot hotter than prior and I think this
would be consistent with a lean condition. This car looks like a million
bucks but runs like a tank.

It sounds as if it is still running too lean. Richer needles aren't
the whole story, the jet heights have to be set properly too, and an
air leak into the intake manifolding between carbs and head are
another likely source of a too lean mixture.
Basic rule of thumb: spitting at the carbs means too lean, popping
and backfiring through the exhaust means too rich. Don't confuse the
six cylinder Healey's exhaust burble with backfiring on this item.
