How to polish & clean valves.

[Dezertxj88]

Well guys I got my valves in, the fella cleaned them up really good! But the exhaust have carbon build up. Intakes look great though.
Anyway to clean these?

Both sides will get polished to help prevent this in the future!

I use a wire wheel mounted on a bench grinder. It can damage machined surfaces, so be careful!

how about soaking them in seafoam or diesel or other?

I glass bead or wire wheel the heads and wire wheel the stems after they go through a jet wash (your dishwasher is kinda one) or sit in a solvent tank. If your valve job was fresh you'll have to keep track of the valves and hand lap, otherwise have it freshened up.

heavy carbon can be knocked off with another valve . then use above mentioned .

This is what I was told lol. Kind of scared me and I thought everyone was just lying

I tryed seafoam for 24/hrs..it got some small stuff off but not much!
I'm either going to use a fine wire wheel, or use my drill press and some fine grit sand paper..gonna enlist my little borther as a spray to spray lubricant on it to not heat up the valve to much!

What I found out is I have Ls6 exhaust valves..slightly longer, but sodium filled! Did my measure and I guess the seller didn't nkow that

Will try that today, any kind in specific? Good news is we put them on a drill press yesterday and I have no bent valves..Guess its time for me to start up a build thread lol.
