So I was just sitting here at work thinking about the cylinder heads I just put on and the different ways I may have screwed things up during reassembly. Then it came to me. Even if all the timing marks are lined up on the cam pulleys, there's a 50% chance that the valves on one cylinder could be out of synch with the other cylinder if they weren't in the correct position when I put the heads on and tightened them down. This seems a little iffy since the valves open and close once per revolution of the cam so if they are lined up (which they are) I should be good to go. But I still have a funny feeling so could someone reassure me on this point? Also, in a somewhat related question, I need to retard the ignition timing due to the new JE 11:1 pistons I just installed and was wondering about the best way to go about it. I recall seeing a thread about this very topic in the past but I have been unable to locate it. As I recall it was either move the timing pickups, or better yet remove some material from the timing trigger (sorry can't think of the right name). Could anyone help me out with that or point me to the elusive thread?
