There are several important reasons why World’s S/R cylinder heads are the preferred alternative to expensive OEM castings or junkyard rebuilds.
First, you should know these heads are designed with extra-thick decks and walls for improved reliability as well as equipped with hardened steel exhaust seats that are compatible with today’s unleaded gasolines. They also come with screw-in rocker arm studs for extra durability. Needless to say, the S/R is substantially more durable than OEM castings.
Secondly, they are fully 50-state emissions legal and because they are an OEM replacement head, they are legal for use by many oval tracks and race Sanctioning organizations.
In fact, NHRA accepts World castings #043600 and #043610 as replacements for Chevrolet 041, 186, 291, 462 and 492 cylinder heads.
World Products SR Sportsman Cylinder Heads are the ONLY heads allowed in the United Rebel Sprint Series!
Valve cover rails have been raised and carefully machined to eliminate oil leaks and the heads can accommodate either early style perimeter or late model center bolt valve covers.
Marine applications are also available too!
Designed for use as replacements for MerCruiser engines based on the small block Chevy, these heads are built to operate at higher temperatures than standard automotive heads and feature Manley inconel exhaust valves and stainless steel intake valves for superior reliability.

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 heads offer
30-70 horsepower gains over OEM heads, yet are 50-state emissions legal
(E.O. #D-343-1).
World has expanded its selection of SPORTSMAN II heads to include special
marine versions equipped with 10° valve locks, Nitrile umbrella seals and
high-temp inconel exhaust valves. They are an excellent replacement for
MerCruiser SBC applications.
Designed for use in racing applications where cast iron heads are mandated or for larger displacement small block street-type engines, World’s 220cc intake MOTOWN heads are the ULTIMATE cast iron SBC head.
Employing RightCast ports, big 2.080” diameter intake valves and a highly efficient 64cc combustion chamber, the MOTOWN provides significant power increases over other heads
on the market.
They are ideally suited for use on small block Chevy engines of 383” or larger displacements.
Available bare or in complete assemblies, as well as in straight or angle-plug configurations.
They’re great out of the box in “as cast” form. With 235cc intake runners they’ll provide ample flow to keep up with the camshaft/intake combinations of most larger displacement small block Chevy engines.
For those who desire optimum performance, World Products offers these heads CNC-ported.
With 250cc intake runners and enlarged, 90cc exhaust ports. The CNC ported heads also boast a larger 2.100” Manley stainless steel intake valves, so you can readily see the kind of power these designs (developed by Kuntz & Company) will deliver.
World Products has taken the Chevrolet’s Vortec-style cylinder head design to the next level with these superior-performing 23° MOTOWN 220cc intake runner heads. Combine these high-flow ports with generous 2.080” diameter Manley stainless steel intake valves and you can see where the extra power comes from.
They’re available bare, or in three different assemblies that are designed to match your camshaft’s valve spring requirements. A multi-angle valve job and Manley stainless steel valves make the assemblies an excellent value and a real time-saver for engine builders.
