Big Horsepower Maker for Budget Racers!
18° Intake & Exhaust Valve Angles

The Brodix Small Block Chevy -18X Series Aluminum Cylinder Heads offer the best of both worlds, 18-degree horsepower without using expensive shaft rockers or offset lifters. This head offers a dramatic horsepower increase over the previous 23° cylinder head. Several advantages of the -18X are intake ports that flow over 320 cfm out-of-the-box, an intake valve size of 2.140, raised intake ports, and shallow combustion chambers. The -18X is an excellent choice for the budget-minded racer who wants to go fast. Every casting is poured from A-356 virgin aluminum and tested before Brodix utilizes their in-house processes such as finish machining and heat treating to assure that you receive the best products for your hard-earned money. The industry standard has been taken to the next level with modernized CNC porting. Other features include a thick deck surface that is compatible with nitrous, drilled and tapped holes on the ends for standard drive accessories, phosphorous bronze valve guides and interlocking valve seats installed. Sold in Pairs. Made in the USA!
