Trick Flow DHC 175 Cylinder Heads for Small Block Chevy Now Available at Summit Racing

You want to wring the most performance possible out of your vintage-style small block Chevy, but those sharp-eyed buddies of yours will spot a set of modern aluminum cylinder heads a mile away, even with a splash of paint to help hide the transgression.

The thoughtful engineers at Trick Flow felt your pain and came up with a solution—the DHC 175™ cylinder heads. They have exterior touches like straight spark plug holes, raised markings on the ends, and a choice of drilled accessory holes or no holes. But on the inside it’s all Trick Flow performance:

• 60cc CNC-profiled combustion chambers with blended bowls
