I pulled these off to swap on a set of trick flow heads. Absolutley nothing wrong with them. They have dual springs, close to 5500 miles since I had them ported. These are ported by prc and are originally a 799/243 casting. Stainless valves, just not sure what brand prc uses. In great shape ready to rock! If you were to buy these outright from prc it would cost 1500 roughly. Looking to get 1000 shipped. Feel free to ask if you have questions
