Default Cylinder Head Question

I was directed to come here for some help.

I have a mercury 1994 Grand Marquis that has a ford 4.6L Cast iron V8 Engine which to my knowledge is the same block that is used in the Mustang GT.
My Drivers side cylinder head needs to be replaced and I cant really find any heads that are said to fit my car and the machine shop that my block is currently at wants around 400 for a used head so I found a pair of mustang GT cylinder heads online with casting number F5ZE and year 96-98.

My cylinder heads have a casting number of F5AE. If I get the mustang head I plan on replacing both heads as to not have an potentially unbalanced engine.
my Question is will the heads fit my block? my primary worry is that the head gasket and bolt pattern may be different. Whats the difference between the F5AE and F5ZE casting numbers?

Heres the link to the mustang heads

Yes, the heads will fit,

idk what you use the car for, if its just an A-B car or if you want some performance out of it, if you're looking for performance go with 99-04 mustang GT heads, might as well throw the cams and intake on too while the heads are off.

If the car is just a point a to b car the 96-98 heads will give you less power (probably about the same as your car stock) but will work.

Its more of just a point A to point B car, extra power would be nice but not much of a concern. Another thing I thought about is my stock intake manifold and valve covers. would they also fit the mustang cylinder head?

everything will swap over as long as you keep it 1998 or older
