Arthur, if you are talking about the intake porting you could send them your used ones currently on your car and then have them port and polish them and wait 1-2 weeks with no car. Most people just go on tousley ford and buy new upper and lower intake manifold and send them out to have the port and polish done. If you are talking about the camshafts they do the regrind to new specs and then you can send them your used camshafts after you put the new ones in and get a $400 core refund.
