RHS Engine Blocks and Intake Manifolds

Racing Head Service - the legendary innovator of airflow technology – offers the ultimate in cylinder head, engine block and intake manifold performance. Utilizing the resources of the industry leading COMP Performance Group engineering and development team and the most sophisticated engine technology in the performance aftermarket, RHS has re-established itself as a leader in airflow design.

Founded in 1967, Racing Head Service began exclusively as a manufacturer of racing cylinder heads. Over the years, RHS grew into an integrated racing company, offering complete turn-key engines and race car parts via mail order. Always an innovator, RHS was among the first to offer “crate engines” and mail order parts, establishing its reputation as a leader.

With innovative cylinder head designs and porting techniques, the company became a performance icon during the 1970’s and ’80s in both circle track and drag racing competition.

In 1976, the RHS management team, recognizing the direct performance linkage between cylinder heads and camshafts, launched a new company – Competition Cams. Throughout the '80s, RHS and COMP Cams became an amazing one-two punch for everything to do with racing. From their headquarters in Memphis, Tennessee, the two dominated NHRA and short track competition with their racing heads, valve train components and engines. Today, COMP Cams has grown to be the dominant force in valve train technology and an established leader in the automotive aftermarket.
