I wouldn't worry about the pointer lining up if you measure it as correct, just fit the inlet cam to std setting, I assume you have pocketed pistons ?

The block is unskimmed. The head is skimmed a lot, but the head gasket is equivalent thicker so it adds up. If i use the std. pulley is messures 110 degrees with the std. inlet cam and 122 degrees on the BD16 cam. One tooth on the cam is 9,4 degrees on the crank so to achieve the reccomended setting at 105 degrees i have to move the cam pulley one tooth as my verniers only can be moved 10 degrees in both directions. Thats not a problem, its just something i haven't seen before. But i guess its the BD16 cams fault, because when fitted with the std. inlet cam its 110 degrees.
