Hi Having had experience of cross flows in Ford's, by your description it could be the timing is out, but if this was the case then I would have expected it to be running hot and a loss of power/ performance. it is more likely that the plugs/valves have baked hard deposits on them due to it not being converted to un-leaded and these are turning into glo-plugs that ignite the fuel.
If plugs have signs of heavy deposits baked on then try new ones that are designed to get hotter. If this does not do the trick it is head off and inspect the valves and take it from there. You do not say how many miles the engine has done, do you get a blueish exhaust when cold, how much oil do you use every, if so and it has done 80k plus miles then you may have worn oil seal rings that are causing deposit build up on the valves. Sometimes on lower mileages this can occur if the car has done lots of short journeys and never gets warm up properly. Hopefully it will just be the plugs.
