Joe - I meant that I confirmed the spark plugs are receiving spark and that the spark plugs work (took them out and grounded them against the head while I turned the engine over). However, when the spark plugs are installed back in, pulling the wire off #3 and 4 causes no change to the running of the engine, whereas pulling the wire on the other cylinders causes a definite stumble. I should note the engine was stumbling during our testing yesterday....definitely feels like it's missing.

So I think that means that there is no detonation going on in those cylinders. That's what I meant by not firing.
Intake valves stuck closed? Exhaust valves stuck open?

Fuel and spark shouldn't be the issue, so that leaves air.
