Hey everyone,
Have a different situation with my newly acquired exhaust manifolds on my 318. So I switched over from headers to manifolds. Installed a set of M body manifolds w/AIR,both ends on the manifolds have been capped off for emissions etc.
Now I take it down to the exhaust shop after they bend up pipes to make up the difference between the headers to manifolds. Go to fire it up and the exhaust guy says you have leaks from the bottom on the AIR holes where it meets up to the head....
