anybody tried this method for clean a engine head or an engine block?

Nope. I've used diluted acid and had that work wonders.

Any particular variety?
HNO3 or HCl?

where is the How-to? :D

i used it on an exhaust manifold a few years back. works pretty well, but it's slow as shit.
for cleaning cylinder heads, i use aircraft remover. stuff annihilates anything carbon-based including, but not limited to: paint, oil, grease, skin, apples, ferrets, red licorice and the non-metallic parts of vacuum cleaners. won't hurt the metal though.
for oxidized aluminum, i use diluted lye to etch the surface/eat the oxidation. cast aluminum stuff usually turns a dark grey (called smutting). you can de-smut it with dilute hydrochloric (muriatic) acid or nitric acid (harder to find, but works better and doesn't harm the AL, where as HCl will attack Al as well).
i got turned onto the lye trick with Al when i started anodizing some of my brackets/custom parts. these are the porsche caliper brackets and 3SGE manifold throttle cable bracket i did a couple weeks ago:

this is the throttle bracket fresh out of the dye bath:

it's really not that hard, just need some sulfuric acid and a battery charger.

Any more info on the DIY anodizing.
I use subaru upper engine cylinder cleaner on blocks and heads, a few cans and an hour and the shit comes up new. :noel:
-
Yeah post a DIY. I want a powder coating setup but currently have nowhere to put a secondary oven.
-
I've used muriatic (HCl), but undiluted it will eat the shit out of the aluminum and turn it grey/black. It needs to be super weak.

there are actually lots of DIY sites for anodizing, a lot of them in the paintball world.
