DC, sorry for the delay....The Goo Gone....gave it a shot swung by LOWES and picked up a bottle and tried it out...sorry though, no affect...rubbed on the stains and even soaked them but nothing...

So to this point I've followed the instructions and used only wood and plastic scraper..Permatex gasket remover and Goo gone...the surface I'm pretty sure is clean with no residue but ugly..I could go against the rules and put my die grinder with a white bristle 3m pad that's made for cleaning aluminum and brush it off...or bite the bullet and install the heads...any help or advice would be appreciated..
