Since I use these for a living here at Crower that is 249/254 duration at 0.050" on a 110LSA lobe lift of 0.365"/0.364" then just multiply that by the rocker ratio to get valve lift. Now that is the obvious stuff but here is the not so obvious info. Look at the left hand side that shows the "Open,nose close ACC" "Acc = Acceleration" that is the second derivative and this info looks not so good. This cam will be prone to noisy lifters and valve float. Notice the open Acc is slower than the closing? well this means that spring set up will be imperative if not critical when going over the nose at anything over 5,000rpm to keep the lifter from slamming down on the cam. I personally would have used different masters than these. This is just my two cents. Ask if you have questions.
