Continuously improved since its 1987 introduction, the World Products Sportsman II is still the industry's most popular cast iron high performance head. Featuring RightCast 200cc intake runners, Fast-Burn chambers and your choice of angled or straight plugs, they're good for 30-70 HP increases right out of the box. They are the aftermarket's only 50-state emissions legal cast iron high performance cylinder head (EO #D-343-1).

Products typically ship out between the same day and 1-3 days. Depending on the time/day ordered and the product type. Some products are made to order to spec and will ship once built. Feel free to call us at 704-871-0721 if you have any questions about shipping. Also call us if you are ordering large items like race car bodies as those are hard for the freight system to calculate sometimes and it will overestimate. Thank you.
