Six or four special washers on each exhaust manifold?
The older small block exhaust manifolds use special washers that allow expansion under the bolt/nut head. I thought I had read in a factory service manual or elsewhere that the two center bolts did not use these special washers, only the two fasteners on either end. However, on Ebay there is a fastener kit that included a special washer for each and every fastener. What is the correct application and why? Thank you.
