figure out your lift by dividing the 1.6 lift by 1.6, then multiplying that number by 1.5
the factory lift numbers on the gm cam is for a 1.5 rocker

This hydraulic roller design contains eccentric for mechanical fuel pump. It is for off-road use only. The duration at .050" tappet lift (intake/exhaust) is 234/242; and maximum lift with 1.5:1 rocker ratio (intake/exhaust) is 539/558. Valve lash is zero/zero and lobe centerline is 112 degrees
I cant wait!! thanks again

Actually vacumm is not the best. I have 11" of vacuum with ported heads and 1.5 roller rockers. Needless to say my brakes suck. Even on wet roads I have trouble getting the ABS to kick on.
I bought a vacuum canister from Summit Racing but never put it on. I'd rather go with an electric vacuum pump.
