I have a pair of these. one cylinder dropped an exhaust. a new seat has been on that cylinder. Guides have had helicoil type inserts installed. cut for stage 1 valves. ports are original, no grinding at all. heads were vatted and checked for cracks before seat was replaced. $200 Paige, Texas I often travel to Ft Worth area and would be willing to meet anywhere between here and there or Austin area. only way I will ship is if buyer arranges shipping and for shopping company to pickup.
