Burnt Valves?

Hey everyone. I have a quick question. The old heads that came off my engine, some of the valves were a chalky white. What does this mean? Are those burnt valves? Can they be reused or are they toast?

Thanks Steve

No that normaly means that cylinder was firing good and not much in the way of oil consumption... Unless they are of a orange burnt dis-colored appearance they should be ok provided not to many rebuilds on them...?

Oh really? Sweet. Ok one more question then. The heads they were on were "126" heads, a smog casting. The "new" heads I have are "370" 300hp heads. My new heads have valves but they will take quite a bit of work to get useable again, just wondering if my old valves {126} will work. The new valves are 1.94 and 1.50. Does anyone know if the "126" heads had 1.94's and 1.50's? Their still in the heads so I cant measure very well.

Thanks Steve

take a socket that fits on the retainer, get an extension, give it a good wack with a hammer. it will release the keepers and allow removal of the valve then just measure with a caliper. I'v managed to clean up some nasty valves, on a wire wheel.

Yea thats prolly the easiest way to go. I know I can clean these valves up but it would be a lot of hard and unessecary work if I could just put my old ones on.

thanks Steve
