i need to replace the head on my car so i found one from a junk yard. it's not as dirty as the one that is in my car right now. but while i have this newer one just sitting, waiting to be installed, i wanted to go ahead and clean it up. is there anything that i can soak the head in to help lossen up the carbon deposits and get the head close to looking new again? im looking to do this myself. more that i can learn about the functions of my car. and what is a good way to clean it up a bit?
