Selecting Mopar Cylinder Heads - Size Does Matter
|
This Indy 440-1 cylinder head has been ported to Max Wedge size ports. Next to a fully ported factory 452 casting the difference is apparent. No wonder these heads make so much power. Notice how the long valve design makes the head physically much taller than the factory unit. Exhaust ports are also raised so exhaust clearance will be an issue in certain applications.
