When porting aluminum use bar soap on the bit or use ATF dip bit into one or the other ever so often it really keep the bit from gumming up. Soap seams to work better for me. ATF or WD-40 adds oil to the pores of the aluminum and if you have to weld on the Aluminum afterwards the oil will mess up the welding just my .02 worth
By the way looks good that is what I did to mine much much better than stock. Keep the slightly rough surface on the ports helps keep the boundry layer smaller on the air flow.
