If you use oven cleaner, Check to see that it is safe for Aluminum. If it is not, it will eat away the sealing surfaces and leave pits.

I would avoid the use of any metal bristle brushes on the Aluminum as they might scratch the surface. Mineral spirits and a cheap tooth brush (possibly with trimmed bristles) sound like a good combination. For the extremely stubborn small areas, brake cleaner might help.

The brake cleaner won't etch or oxidize the aluminum???

The machinist will clean the heads up in his parts washer, I wouldn't worry about that Wes.

X2 We never clean heads. As soon as I take them off, they go to the machine shop, they are completely disassembled, cleaned, inspected, and the gasket surface is machined for flatness. They come back looking like new and it doesn't cost that much. Money well spent IMO.

This is the route I would probably take as well Wes. Best to have it torn down and checked out anyhow.

I have done it both ways Dale and I would them checked by a machine shop and pressure tested at a minimum and go from there , it is around 900-950 to have the heads milled , valve job ,cleaning, etc at my machine shop some may be more or less, if its needed do it , but if your heads are fine its a lot of money to spend if if its not needed.

I cleaned my own heads on my race truck and I soaked them in diesel for about a week , and used fine steel wool , tooth brush , and green 3M plastic die grinder brush to clean and surface the head gasket surface area.

Pushed a headgasket a little while back. Just trying to get my ducks in a row before I take it apart, since I can't afford much downtime right now.

Mineral spirits work alot better than the regular degreaser for parts cleaners? I picked up some harbor freight brand concentrate and it sucks at cleaning, I didn't delute it as much as recommended on the bottle either. I can tell you it doesn't anything like the solvent we used back in school for the parts washer. Maybe they just use a better brand solvent iirc they used safteykleen. But this stuff I am using now absolutley sucks! any recommendations?

I let the machine shop deal with mine and used a rubber bristle whiz wheel on the block to be 100% safe. Speaking of downtime I pulled mine apart Tuesday evening and put it back together Friday night. That's what I would recommend doing so there isn't a lot of time to forget were everything goes and the order it came apart! P.S. Not sure what you are doing but I did my head gaskets in cab....

I was just wondering about a cleaner for everything. Oil pans, intake runners, all the accesory brackets etc minus the heads. I got alittle bit of diesel siphonned out of the truck before I about passed out and used a paint brush with that and it works 30 times better than this degreasor I bought, if that tells ya how bad of a job its doing.
