I'm not even gonna read all this, remove the valve covers and then the rocker assemblies and lay a straightedge across the tops of the valves and see that they are all at the same height...if they are all at the same height then you have a half decent machine shop. now to check lifter preload without pulling the intake, from what you had said an intake valve is open when it should not be....that is not good...this happens all the time when a machinist is not familiar with a non adjustable rocker arm. so at this point in time you are faced with diagnosing what they did wrong and if they have the valve tips all the same height then you have a choice......you can get shorter pushrods but if they are all diffrent then the choice is two of two...adjustable rocker arms and a new machinist...sorry but thats the facts if the valve tips are all the same height then you just need adjustable rocker arms or shorter pushrods...either way I recomend the adjustable rockers.all of you pointing fingers at the ignition system need to remember he had the engine rebuilt not the ignition system go back to the basics and the beginning....start at the bottom...it has fire those who mentioned 5 and 7 being crossed good that is very possible but the rest is go back to the basics and when the do a valve job things change...ignition systems are pretty reliable just my opinion so think what ya want...i'd recheck the valvetrain
