Degree the cam to 106 Intake Center Line and don't worry if the @ .050 numbers ain't perfect. The lifter bank angles and lifter bore axes are pro all off a bit, making the @ .050 numbers off a little.
Verify TDC. Set the dial indicator on the lifter and find max lift. With the lobe at max lift, rotate the crank to 106 degrees ATDC. Put the gears and chain on and VERIFY ICL and correct as you may not be exactly at the center of the lobe.
