I have a 79 20R, but most of them that i have seen have the mechanical fuel pump on the side of the head, but mine has an inline electric fuel pump. I just guessed that someone put an aftermarket fuel pump on it, but there is no block off plate or anything. I'm looking at buying a new head, i think mine is warped, but what head do i have? any help would be great thanks.
my 79 has the pump in the tank as yours should
any 20R head will bolt right up, and i would keep the electric pump
