Yes. The 16V head was only used on a 2 litre block, which is different than
the TR7
2 litre block. The 1850 was only used on the Dolomite 1850 (and S**BS).

>H*nd*.
Yes. SOHC operating the inlet (or exhaust?) valves directly and the exhaust
(or inlet?)
valves via rockers.
The heads are great to look at, angled head studs excepted.
It won a Britsh industry design award when introduced.
>The standard carburetion I think was twin Str*mb@#gs, beloved by Triumph.
Actually twin SU HS6s on a long tract inlet manifold.
>with 4-speed manual.
Same as TR4-6, Triumph 2000-2500PI, different ratios.
Overdrive became stardard fitment too, after a while.
>Everyone expected the heads to .... the TR7, but no,
The TR7 sprint was rallied quite extensively before the V8 could be homologated.
Several production cars do exist, I seem to remember reading somewhere that
the number was at least 20? I saw several advertised for sale in the UK.

They do fit. For an excellent description of how, I would recomend the
TriumphTune
catalog (Richmond Surrey, UK.). They sell the few extra parts required: exhaust
manifolds and system etc. They will also sell you a TR7 'Sprint' stripe set
in silver,
gold or black, as fitted to the production cars.
