    Hi all! During my major some how, I am not sure but I am afraid that I mixed exhaust camshafts between 1-4 & 5-8... It seems that they are identical apart the different part number. So, are they identical or everyone is a match with a given bank? Part Nos not help too much because as per part manual would be 139337 & 139338 however the ones that I have are 139232 & 139233... Any advice would be welcomed.

    With the crank at TDC Cyl 1, lay the cams loosely on the heads with their index markings pointing straight up, Cyl 1 should have both valves closed. Turn the cams 45 degrees, Cyl 5 should have both vales closed (and Cyl 1 should have exhaust valve a little open).

    If it's like the above, then you have the right cams in the right places.

    RH camshaft will end in odd number LH part will end in even number. Applies to virtually all ferrari parts.
