I edited my previous post when I pondered why you thought 302 when I noticed the exhuast port size.
My bad, it's a 308 head.
Or that other part number for the 308.
I bet you were looking at those exhaust ports being spaced out huh? But the 302 should have its casting on the top as well as 714 ..while the 308 sometimes is not or mostly is not actually and is on the bottom and you'll see that 25 cast in and usually a half moon type design or something like that
