Long Branch RA III Headers Bolt to 350 Block

Short answer: Yes — the Long Branch (Ram Air III) manifolds bolt to a 350 block and are a big improvement over the stock “log” manifolds: better flow on any Pontiac V8, better ground clearance than headers, and a more reliable seal. The downsides are the oil-filter location (good solutions exist) and cost (~$400 new, plus ~$150–200 if you ceramic-coat them to preserve them).
