I would go for an aluminum manifold but I really hate to have to change my valve covers too because my valve covers don't have an oil port. Thats why I picked up the quadrajet manifold because it has the oil filler hole in it and would look original on the engine, and it has the original chevy red color. The numbers on it are 3875954, then in another place it says GM3, then a letter "T", and in another place, A126. Is anyone familar with this? Thanks
