I check the LSA angle on the intake lobe at 3 different places .050, .100 and at .200 before and after max lift on both sides of the lobe, once I get the intake exactly where I want it, I check the exhaust lobe the same 3 places to make sure the cam is ground on the LSA they say it is. If it is ground on 106 LSA and installed on a 102 ILC ATDC the exhaust lobe center (max lift) should be at 110 BTDC: scope
I've used Isky solid flat tappet cams that where ground on 104 ILC installed at 99 to 103 ILC, those work great in my old bracket motors up:
