High-mileage 915 J heads... can they be fixed?

It will cost between 400-8-- bucks to have those heads properly repaired....possibly more. They aill need guides as well, I am sure. Guide and seat work is not cheap. Add up guides, seats, valves, springs, retainers and valve locks. Then the labor involved. It's going to get expensive pretty quickly.

Gotcha, yeah sounds like finding another set of heads will be the way to go.

@George Jets I looked into those RockAuto heads some more, the ones that are in stock are the ones with holes for air injection. But l could just plug those holes, and all factory 360 heads are basically the same in terms of flow and such right? Especially for a bone-stock app like this.
