You can check the cam timing with the engine in place - except I don't know how many non-stock bits you have on top. The RHS is usually not an issue but you have to clear some space on the LHS. Enough to mount a dial gauge on preferably #1 and 4 Inlet. But not essential, #2 will do - you just use another crank TDC mark. Make sure your valve clearance on that one is correct first. Otherwise you can do an eyeball check - depends how good you are at judging 1-2mm depression on the valve. You wouldn't set them up like that, but you can check if something has gone wrong, that way. BTDT. Basically you will want to check each bank has same Inlet valve depression at TDC for that valve. Any valve on each bank basically will do. But if you have dropped a tooth one bank will be quite different.
No idea if a turbo makes a difference, but suspect not. The valve timing for the 930 is not greatly different to an SC, depending what cam.
