Hey guys, I'm thinking of buying fenderwell exit headers (Hedman HED-89360)for my 78' F150 with a 351M. Has anyone had any problems installing these headers?. Are they worth the hassle? or are the full length headers the better way to go. Only reason I want fender exit is because I got a set of side pipes that would look deadly on this truck:smokin:. Thanks for the input.
