RHS Pro Action LS3 Rectangle Port Cylinder Heads

RHS Pro Action LS3 rectangle port cylinder heads are premium replacement heads that utilize the same architecture as factory. This means all stock components will fit without modification. These heads feature factory-correct intake manifold alignment slots—ensuring that the intake manifold ports line up properly with the cylinder head ports to avoid power-robbing misalignment. RHS manufactures these heads from premium materials and machines them to the industry’s tightest tolerances. They’re available in bare, assembled, and complete but unassembled models.

Features:

* Premium bronze/manganese valve guides for long wear with particular focus on precise tolerances on valve seat concentricity
* Clean Cast Technology eliminates casting flaws and promotes a smoother internal surface finish for greater air and coolant flow
* Dual seat spark plug pocket design allows both factory style tapered seat spark plugs and flat seat style plugs in wider heat ranges
