454 Engine
Hi, I know I might sound stupid but I have a problem. I have a 454 out of a 1971 - 1975 truck and It came with a wieland stealth intake manifold on the side. I went to install and found this wierd square looking ports on the heads. regardless to say when i went to match up the intake and the cylinder heads the intake did not have any ports matching up to this thing. I enclosed a photo to show you the type of head I am using.
