Q: Long Branch RA III Headers Bolt to 350 Block
Will long branch RA3 headers bolt up to a 350 block? Mess with performance good/bad?
A: Compared to the stock log manifolds, the Longbranch units are a big win. About the only negative would be dealing with the oil filter location, and there are good solutions to that, and of course, the cost. At nearly $400 new, these aren’t exactly cheap compared to headers. Plus I’d prefer a ceramic coating to preserve them and that would add, what $150 – $200 to the overall cost? On the plus side, better flow on any Pontiac V8 over log manifolds, better ground clearance than headers, and also a more reliable seal. Not that you can’t get headers to seal well as long as the flanges are straight and you use high quality gasket (Felpro metal core, or copper seal).
