Out of curiosity, what would 1.94s have been used on?

Do those heads have a machined pocket on the intake side or I'll re-phrase, should they? Do 462 and 291 heads (2.02) have machined area around intake valve? My only experience with 2.02s are 186 and 492(over the counter) heads I have had and they are machined. Usually a good way to tell if that is the valve that came in head opposed to being modified.

No.  If you were to take, for example, 186 heads with 1.94" intakes, and have them machined for 2.02 intake valve size, then you would also want to ask them to machine to 'unshroud' the valve.  Hope that answers your question.. :)
Note:  I really like the 1.94" valve heads on the street better than 2.02, as you'd have to be running very high rpms to justify the larger valve size.  1.94" run better and are more efficient for 90% of street driving.
