working on my 84 wagon with mostly rebuild 258 kept stock(less than 4,000miles)... a neverending project... just had to pull out both manifolds to get to the o2 sensor that was stuck... anyway while it was appart we noticed that i had a few spots where the exhaust gasket was blown and it seems that the manifold is slightly warped...
that said Id love some input on what others have done or would do given the chance
I've seen shorty clifford headers (57-2300 "6=8 HEADERS") and shorty blackjack dynomax headers (DYN88739) both dual exhaust and would need some modification to the rest of the exhaust....
