Re: Choosing the right 289 or 302 Heads?

Be wary of GT-40p heads off of Explorer 5.0 engines, they have a modified spark plug angle and can cause header fitment problems.

Standard Cast-Iron GT-40's off a 93-95 Cobra would work well, flow a little better than a K-code 289 Hi-Po head does. Should bolt right on, you will want flat top pistons to keep your compression at or a little above 9:1.
