They should have SC stamped near the valve cover bolt area. 96-97 NA heads are supposed to be the same as SC heads, but have smaller bolt holes on the intake side.

Here is a picture of 89-95 NA heads. Notice the cooling passages are bigger.

Here is an SC head: they have less cooling ports around the chamber.

I think they do too, here's mine. There's an "SC" stamped in the front/top of the head...

The 89-95 NA heads are on Mustangs, T-birds, Cougars, Taurus , and a few more makes.

SC heads are the better design. The NA heads blow headgaskets at a higher rate than the SC.

They will match up but they are prone to blowing head gaskets. I would not recommend using them.

Uhem. Dave, I think you should rephrase to "They are MORE prone to blowing head gaskets."

The SC heads are prone to blowing HG's, but I agree that the NA versions are MORE prone to it. ;)

...Just being a smartass.

Sorry,

Sean
