We have natural gas cylinder heads rebuilt and ready to go with exchange. All the cylinder heads have hardened exhaust seats, hardened exhaust valves, new intake seats, new intake valves, new valve springs, new valve spring keepers. Heads have all been surfaced. If we don't have a set of cylinder heads that you need ready to go, give us a call and we can try to make it happen.

Ready to go:
