Summit Aluminum SBC Heads

These heads worked out very well on a stock 350 CHEVY SHORT BLOCK that I put together with a Lunati cam,Edelbrock Performer RPM intake & Carb.Great buy for the money if your building a mild street engine in my opinion.

Performance over stock is night and day. Don't like the rails being 3/8 taller casting is pretty rough. But over all better than the competitors in the same price range.
