Cleaning cylinder heads

[oh34v6]

I finally have some time to work on my engine build up, so I tore down the aluminum cylinder heads that I'm going to use today. The exhause ports have a good amout of carbon build up, so i was looking to soak them in my parts cleaner for a while to clean them up before porting them. I was just wondering what kind of a detergent i should use with the aluminum? I've heard to just use dish soap but is there something that would work better?

6 gallon bucket with 5 gal of Formula 88 works perfect, and it's bio-degredable. Get it at Home Depot for $7/gal. Takes about 2-3 days. Then we sandblast, machine, then soak in an alkaline bath for a short time.

Do you sand blast the ports? My dad has a sandblaster in his shop so if its a good idea to do then I might try it. I wasn't planning on doing anything with the valve seats though, as they look pretty good. Thanks for the help by the way.

What works for me is Oven cleaner,one thing don't let it soak too long or your aluminium colour would change to dark grey.
