Guys, I have a set of twisted wedge alluminum heads that I removed from my engine. I need to know how you guys cleaned them up before installing them back on. People have said that they used wire brushes on iron heads, but I would imagine that would not be a good idea on alluminum. would the back of a spunge be soft enough to use on alluminum??
please advise
