Ok with the actual spec aside, is my reasoning behind this whole process correct? I mean in the end with the cam timing all set correctly(say 1.5mm for this instance) it should read 1.5mm AT Z1 on cylinder #1, then if I rotate the crank 360 degrees it should read the same 1.5mm on cylinder #4 AT Z1. The emphasis on having the lift spec arrive at Z1 on each bank during the appropriate phase....

NY82SC,
At TDC (Z1), it could be either compression or exhaust stroke. You want to be at the compression stroke. For cylinder #1 @ TDC (Z1) compression (zero @ dial indicator)........... turn pulley 360°.......gives you the valve over lap for #1. At this point, it is cylinder #4 @TDC (Z1) compression (zero @ dial indicator)............another 360° rotation of the crankshaft pulley gives you the valve overlap for #4. Are you using two (2) dial indicators or just one? Please take note of the positions of the two (2) cams when you do #1. Both
'930 markers' should be pointing upward. The value you get for cylinder #1 (say 1.5 mm) is independent to the number you would get on #4. Both cams have to be set correctly to obtain your target values. Keep us posted.
