World Products Small Block Chevy Sportsman-II Cast Iron Cylinder Heads The Easiest Way to Bolt On 30-70HP! Completely Race Prepped, Ready to Bolt On!

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). You should also know that all World Products heads are precision CNC-machined, and indexed off the chambers to assure perfect alignment with the cylinders. Only World offers complete assemblies with Erson stainless steel valves and other quality components including springs, retainers and keepers.

The industry’s most popular true high performance cast iron cylinder head has been continuously improved since its introduction over 20 years ago. With 200cc intake and 69cc exhaust ports, World’s Sportsman II cylinder heads offer 30-70 horsepower gains over OEM cast iron heads, yet are 50-state emissions legal.
