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

Excellent, I'm going to go ahead and place an order for those RockAuto "smog" heads then. Thanks for all the advice guys, this will save tons of time and at $582 total cost including shipping and core charge I'll probably still be saving a few hundred bucks over having my heads machined. FABO rules!! :thankyou:

Not to mention I'll have a spare set of J heads to mess around with in the future or sell if I feel like it.
