Don't worry about it. Just line the head up by laser eyeball and lock it down. It will be fine. These are decidedly NOT swiss watches. I've installed EJ heads with no alignment dowels and never had a problem at all. Obviously line it up as best you can by eye, but don't sweat it being missing. GD

Usually you would use a dwell meter to set points. But you can use it to check the electronic ignition. You're not setting anything. Just looking for a signal to the coil. In customer pay situations I couldn't just sell them both coil and igniter. We had to determine the cause. Quick test proves the failure. It's easier and faster to test for dwell than ohm out a coil. As the coils were internal to the distributor.

Sure thing, today I confirmed a bad ignition control unit with my multi meter. Checking for dwell at the neg - contact of the coil. Multi meter is set for 4 cyl dwell. While the engine would start due to no ignition spark the dwell reading was 0.0 meaning there was no signal to the coil to fire. Meter is connected from yellow wire(red positive) and engine ground (black meter led) with ignition off it'll read about 60°. Not that important. When ignition on it'll drop to zero(power on, no signal) during good start it'll jump up(doesn't matter how far, just means you have signal) with failure the it'll remain at 0.0.(no signal). Found an ignition control unit on Amazon for 27 beans. Woooo!
