I don't know that you will find a "diagram" like what you are asking for, but I can tell you that the longer pushrods go on the Exhaust Valves and the shorter ones go on the Intake Valves.

I have a 1999 Buick Century V6 3100 that I had to replace the intake gaskets due to antifreeze leaking into and out of the engine. When I had it all apart I noticed the very first lifter #2 cylinder...

If the engine oil was full of antifreeze when the intake gasket went bad, then there is a good chance that there may be some cam and/or lifter damage. A more likely cause of your problem would be that the push rods got mixed up when you put it back together. The intake and exhaust rods are different lengths. If this is the case, and you have turned the engine over, there is a good chance that you now also have a bent pushrod and intake valve. The exhaust pushrod is the longer one and if you mix them up, the piston will contact the intake valve because it will not be able to close due to the longer pushrod. This will bend or break the pushrod and bend the valve stem.

On the 92 chevy lumina eurosport 3.1 push rods on the heads you gave the configurations but no matter which way I put them in the long is too long but the short is too short. also when I tighten them down...

the euro sport is the same as the lumina base just with a body kit, stiffer suspension, and dual exhaust.

but on the 3.1 engine the pushrods are all the same length, but depending on the stroke each cylinder is on the pushrod may be in a different position.

you are assuming that every pushrod should be in the rest state. that is not true. if the cylinder you are installing the pushrod for is on the intake stroke when you install the intake valve pushrod and tighten the rocker arm nut the valve will procede to open like it should be open for the intake stroke.

this is normal and its nothing wrong with it.
