'71 intake won't work with 6X heads, unless the passenger side blind hole is filled, tho some say that a piece of thin stainless, in the correct shape, will make it work.. '72 intake will work. and the RPM will work.

With the 1.65 rockers, an 041 clone cam with Rhoads lifters has been a very popular combo, for many years. Don't know how much lift you wanna run. But, if the cam has .500 or more lift with 1.5 rockers, that puts the lift well over .500, with 1.65 rockers. The stronger springs required for bigger lifts might cause more stress on the entire valve train, which many consider unnecessary with a mild to moderate street car.

If most of your driving will be under 5000rpm, a cam/rocker combo with around .500 total lift, might be plenty, and easier on the valve train. But then many here don't want any power left on the table. So, it mostly depends on what you want.

A Lunati 10510312 will have near .500 lift, with a little over 220° intake dur @ .050 lift, using 1.65 rockers. Should make great low end torque, vac, and plenty of power to at least 4500rpm. Max hp ? No.

If my math(using a calculator) is correct, the intake lobe of a Howards 410051-14 cam would have .528 lift with 1.65 rockers, the exhaust lobe of a Summit 2802 cam will have almost .537 lift, with 1.65 rockers. The ex lobe of a Crower 60243 will have aprox .543 lift. The ex lobe of a 268 Voodoo will have aprox .554 lift. The ex lobe of a 276 Voodoo will have aprox .580 lift.

Just curious as to how much total lift you want or would be OK with.
