Anyone farmiliar with hks camshaft types for 4age?

I have a big port with the same HKS cams. But I believe that the stated lift is actually 8.3mm on both cams. The 8.1 is the valve max opening after the lash clearance is taken into considation. I'm not running with TVIS system on engine and I have a very good exhaust system. With that in mind, the intake cam is set 3 1/2 degrees advance and the exhaust camshaft is 1 degree advance which helped improve the lower end rpm torque.
I would not be concerned about the difference in lift. You are not going to see any real difference between 1 or 2 tenths of a mm in cam lift.
Do not try to degree in the cams at max lift. Set up the cams by reading a equal lift on both sides of opening and close ramps.
