View Full Version : talking propane heads.

What exactly needs to be done in order to have long lasting propane heads? Ive been told i only need hardened valve seats to full blow sodium filled valves, anti-spin retainers, hardened vavle seats and more.

Could someone clear the air? Thanks

Yep, just seats are ok. Any vehicle built for unleaded fuel only will have heads up to the task. Dunno about any other manufacturers, but GMs unleaded heads used "stellite" seats. These were hardened steel to combat wear once lead was removed from gasoline. Keep the valve rotators too. They'll keep the valves wearing evenly.

Don't think I've ever seen a stellite seat in a GM head, all they did to their cast iron heads to combat unleaded fuel was induction harden the seat area. you can use these heads with propane but the rotators must be removed, else the valves will recede into the seat.
