What headers will fit???

Just talked to my installer about this.....and he mounted the engine like this on both sides.....strange that this is wrong tho considering that everything except for header fit smooth....transmission mount lines up and bolts in perfect....but from what I see above this is wrong....now if I unfortunately move it is will need to repatriate radiator support and reinstall for clearance reasons.....and I'm guessing I will need a new driveshaft made longer....and idk if Trans will still line up
