1.6 ratio BB

yes on all the above.
going to 1.6 is supposed to be worth 10-20 HP depending on rest of build. 1.5 to 1.6 adds approx 3 degrees duration at .05 lift, so then check the "intensity" by subtracting the new .05 duration from seat duration. Don't want the result to be smaller than Voodoo/CompXE numbers. So they say the rocker ratio change should not be done/wont work out if you already have a fast acting cam. But...I notice the CompXE solid lobes are the same for Mopar/Ford/Chevy meaning those lobes will handle any rocker ratio 1.5 to 1.7. Just food for thought.
