You have to make sure you get the lifter on the flat part of the cam when you adjust it. With these high profile, long duration cams most of us use, the standard practice of rotating the cam to TDC on #1 and then setting half of the valves, then rotating to 360 out from TDC and adjusting the other half usually won't work. It's a pain but you really need to rotate the crank to TDC for each cylinder and adjust the valves there. Keep in mind that, by conventional agreement, the duration measurement for the cam lobe starts where the lift is already at 0.050 inches. You have to get the lifter sitting on the lowest part of the lobe, which is 180 camshaft degrees (360 crankshaft degrees) out from the high point. If you don't do this, your clearances will not be correct, and it will show up as too much clearance when you check later.
