C5 corvette problem

Hey guys so im running into a little trouble, started with a misfire I thought it was the spark plugs changed them out nothing changed coil packs nothing changed spark plug wires still nothing and it all started when i installed longtube headers and removed egr valve and air injection system, car is tuned already, and earlier today i noticed cylinders 2,4,6,8 are dead (passenger side) any help would be great

Maybe the ground wire was disconnected at the back of the cylinder head and not reattached during the header installation?

The c5 has an AIR system which is very similar to an Egr system. @C5 Diag just likes to get fancy in his responses. Lol.
