340 Aluminum Edelbrock Heads & Intake Deep corroded Appearance

Just regular old oxidization. Aluminium wheel cleaner. Its an acid. Be carefull around other objects.

THIS... I used Eagle-1 Etching Mag Wheel Cleaner, dissolved all the nastiness off my aluminum heads and intake and after rinsing with a pressure washer they looked better than new with a fresh surface for paint to adhere to. I don't have any 'before' photos but they had lots of ugly brown-gray corrosion and oil/dirt on the cast surfaces.
