The shop i bought them from did a valve job its not the factory job, they only have 2 clutch test runs no track time . I was thinking if i bought new exh valves and lapped them i could see if the seal area looks uniform. I dont wont to reuse the bent valves. This is on a pulling truck and if i send them to shop it will take a few weeks usually(no matter what they say) i will miss a few pulls if i do that
