I'll guess that this is the "standard" Mk.3 Spitfire style of intake and
carbs. The Smiths PCV valve just fits in the hole on the top of the
manifold. Of course, it should fit snugly. If not, one can very
carefully use a drift and hammer to "peen" the inside edge of the
manifold just a wee bit so that the valve does stay in place. The cars
tend to run very poorly with the vacuum leak caused when the valve comes
loose, and the peening method is something my local 'Murrican car
mechanics showed me many, many years ago.

Probably.
Sorry I can't help on needles.
