I pulled the valve covers on the 454 and recorded the casting numbers on the heads. As I posted elsewhere recently, the engine is a 1971 LS5 365 hp originally in a Chevelle.
The vintage Weiand intake manifold (PN WCPSQ) is for the large, rectangular port heads. My heads are oval port (casting # 3993820, 1971 365 hp LS-5, Open Chamber, 113cc Oval Port heads).
The engine runs great; no known issues. Is this port mismatch to be concerned about?
