Headers and exhaust
#43
couple questions on the install of the headers. I am useing new GM gaskets. I was reading up on it and this mite be out dated. Do I need locking header bolts or will the old stock GM bolts be fine? Dealer said they would install them for $110. manifolds only bill out for 1hr. beats doing them on the cold concrete with slush falling off the truck. Anything I need to know about the install
