World Castings  Cast Iron Cylinder Heads

SB Chevy V8 Cast Iron Cylinder Heads

Save money and time by using stock style dart replacements castings and assemblies. More often than not, you will spend more in trying to find good used set of heads and having them cleaned, crack tested, and rebuilt than it would cost you by just purchasing these dart castings in the first place. I've discontinued searching through junkyards for good heads, since many already have cracks, and you don't know until you already have disassembled and cleaned them up and crack checked them. If they are cracked, if the guides are worn and if the seats need replacing, you may have to go through all that hassle again! And without further inspection, they may already be milled down too far to allow for a good clean up, resulting in leaking head gaskets. Before you even know it, By the time and money you spend, traveling to and from, when you finally get a good set of castings, you would have done better by purchasing these dart heads in the first place. They actually come out cheaper in the long run, since, where are you going to find those 2.02 small block heads?   Most junk yards are pretty picked over all ready, and when specialty parts do come in, they usually go pretty fast to rebuilder shops. We are a distributor for World Castings/dart, if you want the best prices around for great heads, give us a call, since we pass our factory direct savings on to you

The added height provides extra clearance for stud girdles and rockershaft setups. A taller valve cover gives a more muscular, distinctive look to your engine. The Sportsman II is the only cylinder head available that accepts both early (rail mount) and late model (Centerbolt) style valve covers. Valve cover gasket surfaces are fully machined for a leak-free seal. To complement the dual valve cover bolt pattern feature, accessory pads are machined, drilled and tapped to accept all early and late model accessory brackets.
