Found the misfire after replacement of gaskets . Holy crap number 5&2 cylinder are dead no compression. Checked the lift of the cam that was good . Put air into the cylinder found to be leaking out of exhaust and intake port

It sucked the intake valve into the head what would cause 1 cylinder to do that

Not sure to be honest why it did that. Post some pictures if you can. Are they 325?

Should be on the front of the engine one one of the hoses by the water pump of the engine. I can only imagine the intake gasket was bad by#1cyl also.
