Now you got me thinking (danger mode).
My guess is yes. It makes sense to me. Seems like the manifold studs
are also double fine threads. Personally I can't recall ever seeing
studs used for the heater valve, but then it hasn't been a big item on my
check list. For as long as I can remember, my MGA has had fine thread
1/4" bolts holding the heater valve. I do know that the threaded holes
in the head are quite shallow, making it difficult to get the bolts just
the right length to work. For that reason alone I would think it best to
fit studs for this aplication.
