How to clean carbon from valves?
How to clean carbon from valves?
I recently over heated my LT1 and warped the heads.
I Just got them back from the machinist. Now that their flat, I'd like to clean up the valves and rods. They have a lot of carbon and it looks like they have burn marks.
Is there anything I can do to clean them up? I was thinking about using a degreaser and a power washer. Then maybe hit it with an aluminum pollish with a metal polishing pad on a dremal.
I'd like to do this to the intake manifold and block (piston head / walls) as well, since I have it off and exposed.
I dont have the cash after the milling and gasket sets to get a value job done but I'd like to at least clean it up.
Any ideas or warnings.

I think you should leave them alone, it's very easy to damage the aluminum surface and the more you handle them, the more likely this is. Cleaning assembled parts like that is a bad idea as it removes the lube from the guides, etc.
The bores should be filled with paper towel and wire wheel the deck to clean it off - do not by any means use an abrasive pad to clean the decks of any metal.
Some pictures would be helpful to access condition, but really if there was something wrong that would cause you problems the machinist should have told you about it.

Here are the images I promised, they are over 2mb each at 2592 x 1944 dim. so they should be big enough to get some detail.
Thanks for your help.

Wow - that motor is pretty abused, lots of cooked oil up there. Did they pressure test the heads, check the valve seal and spring pressure, when I ever see them that cooked a surface is just the least of what it needs.
