Exhaust Manifold Bolt Set, Long (8 bolt set) Black Flange Head Hex Bolts
Exhaust bolt kits come in half-sets of 8 bolts, short or long. Most early manifolds need 1 kit of long bolts per manifold (2 kits per engine).
Most late manifolds need 1 kit of short bolts per manifold (2 kits per engine). Some manifolds alternate long / short bolts, so require 1 kit of long bolts and 1 kit of short bolts per engine.
These kits do not have the bolts with studs sticking out for mounting the heat shroud for the cold start tube used with stock air cleaners.
These kits are only for ’68-’85 472 / 500 / 425 / 368 engines. They will not fit earlier engines such as the 429.
