Exhaust manifolds for an L31 swap from 350? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I didn't clarify in my first post above - my Impala has a 355 SBC with EngineQuest (EQ) heads, which are new castings that are basically exact copies of the GM Vortec castings. I have the inexpensive Dorman (Chinese) reproduction 2.5" rams horn manifolds on it. They look great and work great with the Vortec-style heads.

Off-topic, but anyone building a performance engine should research the EQ heads. They are really nice heads, and a great value.
