to add up your lift you simple take your lift on your cam divide it by the stock ratio of the rocker arm which is 1.7 and whatever the number you come up with then times what ratio you are wanting to that number to get your overall lift for example

if your cam has .525 intake lift take .525 / 1.7 = 0.308 x 1.8ratio = your new intake lift would come out to .555

same goes for the exhaust... .535 / 1.7 = 0.314 x 1.8 ratio = new exhaust lift would be .566

Hope that helps.. and Free Bump
