1.9's are nowhere near the lift you noted. Stock Cam profile is. 278 or. 530 lift with 1.9's. And for power, the Cam is the best way to go. As Scotty mentioned, high ratio rockers will only pronounce the Cam profile, provide sliglty better ram rates and more air in/out. But power will come from the duration and lobe profile, etc. You can go Cam and rockers if done right, I'm running Overkill BBC Cam and 1.8's right now and absolutely love it!
Just take some time to do the research, these engines have no unicorns and the maps are there for what you may want to build, power, street, track, SC, Turbo, etc. It's all there, no mystery!
