I'll see what I can dig up. Yeah, these are older heads I believe were replaced by the x head. If I remember right they're basically aluminum gt40's.

The only difference between the Y-303 heads and the X-303 heads is the Y-303 heads are studmount.

These heads were the first set of the 303 series. The are per mount heads. So these have been converted. Also they have a slight smaller ports than the x head. I need a set of heads for my bronco. Offer ya 500$ pm if your interested.

There is potential in the heads with lots of work and you also have to sleeve the pushrod holes on the intake ports.
