well from the pics posted they look fine unless there is something that I cant see from the pics. you forgot to mention all the other information. just how is it you can tell they were ron hot from the pics. and if you think they are warped put a straight edge on them. dont need a machine shop for that.
a machine shop will be the only one to really tell, but dont be acting like I dont know what I am looking at lmfao what the fuck is that I am an ase certified mechanic and have 10 plus years machine shop experiance, and have been drag racing for 25 years. if the valves are white probably lean. they look tan in the pics
