Doing a hci swap on my 89 gt. Trick flow 170s, stage 1 came, trick flow valve train, performer 5.0 intake. My problem is the intake gaskets wernt matching with the intake ports the way i would like them to. (Fel-1250) im real particular and its not off by much, but if it has any problems in the future ill revert back to not fixing this hahah. Can i trim these? And what is the easiest way to do that? Thanks in advancw for the help.
