Many plating companies offer hard anodizing services, but would be tough with heads that already have guides and seats installed. It's basically a 'dunking' process.
Be forewarned, hard anodizng also makes the aluminum surface very 'hard.' Machining / grinding / porting / etc a hard anodized surface is very tough.
Last warning, it makes aluminum 'electrically dead.' Make sure to leave an accesory bolt hole or two or all unanodized so that you can ground your heads. I would also suggest to keep the spark plugs threads unanodized too as your plugs need a good ground.
We want the heads to be protected from water/electrolysis but we do not want our ground paths gone.

Again, they call this anodizing 'Hard Anodizing' for a reason. It makes the surface very 'hard' and not to kind to cutters, burs, and etc.
