Will 2 valve headers bolt up on 4 valve?

Im doing a 4 valve swap in my 01 GT, I compared my header gasket the the 4 valve heads and they look similar. My question is will 2 valve long tube headers work on my 4 valve heads or do they have different ports or is the 4 valve engine alot wider that the 2 valve? Anybody have any experience with this?

NO, the exhaust ports are different on a 4v.

Just wondering havnt had the manifolds off and they looked so similar on the outside. If I buy long tubes for the 4 valve will they match up to my catback? Or will i have to change out my whole exhaust system?

they will match up to your cat back if you get the correct mid pipe for the brand long tubes you are using. if you mix and match brands you mid have to do a little tweeking
