340 HP exhaust manifold installation ? - 06/05/08 09:01 PM
I am installing the 340 HP exhaust manifolds on my 1970 Challenger. The factory service manual says not to install the conical washers on the center ports for each side. If I put a washer on the center port bolts there is only about 3/8 of threads to engage the head. I purchased a reproduction bolt set so this leaves me with four extra conical washers. Is this correct?
