mine look like the na heads. what are they off of. and are they as good as sc heads?cougarsc said: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.
what about the water jackets will they match upcougarsc said: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.

XR7 Dave said:They will match up but they are prone to blowing head gaskets. I would not recommend using them.
