Can a plug be bad even if it appears ok? Just got done running at the track for a few passes after my head swap and on the spray and on the drive home it started missing?? not bad just at like 3k rpm it has a little miss like on one cylinder. Pulled all the plugs and they appear normal. There cheap so I guess ill replace them and go from there.

Any smoke?

Anything is possible, but, not very likely. There are other parts of the ignition that could have the same effect.

double check ur wires

well my friend had kind of the same experience with his lt1 camaro but it was all motor.
what we had to do was replace the thermostat head coolant return line and fix the loose plug wires...

no smoke, wires are good, and I wont be able to change the plugs till this weekend when im home from school. if I put the plugs in and I still have the miss, i guess thats gonna open up a whole new world of problems??? I just installed my new heads a couple weeks before, havent lost and coolant but could I have blown the head gasket?

if you can't see a **** load of white smoke then you don't have a blown head gasket dude.

maybe there is a problem with the gaps on the plugs i am not sure but you have a lot more power then stock and it might not be burning it efficiently

Might not hurt to do a compression test.
