Yeah but you can get polished intakes, chromed coils, efi and  black and chrome valve covers and big-ass air cleaners that say 'ROUSH' in big letters on 'em.
Takes a lot of design engineering to make that stuff. So's everybody in the parking lot can get wowed by that. That's what counts-they can see you wrote the big check.
Clearances? Ring tensions? Valve guides? Spare qt of Royal Purple in the trunk?; not to worry. You'll make it home.
