I have GT40 heads i was going to install on my car with a B303 cam and 1.7 roller rockers and after consulting two different custom cam grinders they both recommended getting the B303...Which must mean something since they willingly gave up business.
A B303 cam with 1.7's is pretty much the max in terms of lift without stud mounted rocker arms/stud conversion and with the GT40 heads should give you a ton more power, although if you want a tame street car the stock cam with 1.7's really isn't all that bad.
