I forgot to mention that you should use a set of solid lifters and pushrods to check the valve to piston clearances with light weight checking springs when checking the lobe timing, sorry The hydraulic lifters can and usually will collapse without oil pressure giving you a false reading
Another check you can, and should do, is to check the exhaust lobe timing after you get the intake lobe where you want it, the exhaust lobe should have the exact same amount of advance that the intake has, IE cam is ground on 108 lobe separation angle and you install the intake lobe at 104 ATDC, the exhaust lobe should be in at 112 BTDC I have had several cams over the years that where not ground on LSA that the cam card called for
Good luck on yours
