Im not sure what year, make or model car this is, the most common reason for a no start after an intake gasket chage is due to installing push rod in the wrong spot, this is mainly ture on the 3.1 and 3.4 and 2.8 and some other engines, the intake and exhaust push rods are diffrent sizes, i belive the exhaust valve uses a little longer pushrod than the intake, remove the valve cover and remove loosen the rocker arm and pull the first two push rods out, see if they are diffrent sizes, if so then install them in the correct location,let me know the result good day.
With the Engine in the number 1 firing position, adjust the exhaust valves for cylinders number 1, 3, 4, and 8 and the intake valves for cylinders number 1, 2, 5, and 7. Turn the valve rocker arm nut counter clockwise until the valve lash is felt in the valve pushrod. Turn the rocker arm nut clockwise until all of the valve lash is removed (zero valve lash). Zero valve lash can be felt by moving the valve pushrod up and down between your thumb and forefinger until there is no more up and down movement of the valve pushrod. When all the valve lash is removed, then turn the valve rocker arm nut clockwise 1 additional turn (360 degrees).
With the engine in the number 6 firing position, adjust the exhaust valves for cylinders number 2, 5, 6, and 7 and the intake valves for cylinders number 3, 4, 6, and 8.
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.
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.

try putting in 1/2 once of oil in #2and#5 turn engine over for 2 seconds then hook up the compression gauge and check compression if there is then the cylinders got wash out if compression doesnt come up you have broke the spring or bent the valve.
