Are you getting spark in those cylinders? Fuel?

valve lash wouldn't do it, they would have to be so out of whack that you would have major other problems first. Have you wave formed the Cam/Crank sensor? If it is faulting it could be giving the wrong firing trigger to the ignition module, and only fire on one "bank" instead of both.

could also be a faulty ignition module. I would whip out the ole red brick and start diagnosing primary ignition components.

Just because the hole is getting spark, it doesn't mean it is a strong enough spark. That is where some spark testers fall short as they don't have a true resistance. I'm assuming you don't have access to something like a VAT-40 or anything to check the firing line on your plugs.

fuel + compression + spark = combustion. you must not be getting one of these. I would recomend some starter fluid to see if that makes it pick up, if it does you know it is a fuel delivery problem. if you have a timing light hook it up to the spark plug in question and see if it fires.
