My '67 Valiant 100 Big Block 4 Speed Restoration

StrokerScamp told me the perfect set of manifolds for a big block A-body would be C-body driver side and B-body passenger side.

Unsure if that will work though on a 413, it should though, im 80% sure. If they bolt onto the engine, they will fit, just unsure the bolt on part. Maybe someone will chime in?
