Old school Hemi charactor & breathing coupled with LS technology. Ooh, baby!
For GM LS owners looking for the final word in cylinder head performance, Nick Arias Jr. Racing Components presents its new LS-AH Chevy Hemi® cylinder head. Poured from 356 T-6 alloy and featuring full water jacketing, the LS-AH Chevy Hemi will bolt on to any GM LS factory or aftermarket block.
High efficiency ports, along with 2.260-inch intake/1.600-inch stainless steel valves yield more than 400 cfm for the intake and over 300 cfm for the exhaust at 28 inches of water. Choose from either a true hemispherical chamber or Pro Stock-inspired Figure 8 chamber with quench pads–both designs feature a central plug location for maximum combustion efficiency. Heads are available assembled as part of a complete kit, which includes shaft rockers and tool steel springs, cast aluminum valve covers, head gaskets, fasteners and header flanges ($9,036) or assembled heads only ($4,460). Options include CNC porting, black wrinkle or polished valve covers, carburetor or intercooled supercharger intake manifold, and more.
