Exhaust head 4.0 to 3.0 fit

[EthanBuck]

Yes I know dumb question but would a exhaust head from a 95-97 4.0 fit a 3.0 it’s a performance head so i’m wondering if it would help, I just got a 3.0 02 and don’t want to mess too much but i want to open the exhaust and TB up for fun
And if there’s any good tips for a 3.0 that would be awesome i’m planning on getting the cooling system flushed soon and the cps changed

Are you talking about an exhaust manifold?

Yes Mostly asking because looking at pictures they look fairly similar for bolt holes

Ok... headers

I don't believe they will fit.

That’s a shame they look bolt pattern so close

I've never read that they interchange. Probably easiest way to check is compare gaskets in person at a friendly auto parts place.

bore spacing/distance between cylinders is 4.760" on a 4.0, 4.330 on a 3.0
a difference of 0.43" or 7/16" or 11mm

you any good at bending pipes?
