These RHS Mopar Indy 360 X cylinder heads are designed for both small block LA and Magnum engines. With a host of additions and improvements over the factory originals, they give you the flow capabilities of reaching 400 to 550 hp out of your Mopar-powered street machine. The RHS Mopar Indy 360 X cylinder heads come with an extra-thick deck surface to enable angle milling for compression. They are drilled for the proper valve cover and gasket and contain both Chrysler LA and Magnum accessory holes on both ends of the head. Dual pattern exhaust bolts for stock applications or aftermarket W2 header flanges are exclusive features of these cylinder heads.
