FLOTEK's 290cc big block Chevy cylinder heads with 112cc combustion chambers are recommended for moderate street or street/strip BBCs with displacements up to 509 cu. in. operating at or below 6,500 rpm. It may be necessary to check clearance and slightly modify some domed aftermarket pistons due to the efficient heart-shaped combustion chamber on these heads (most of the newer designed dome profiles will clear). FLOTEK recommends removing material from the piston and not the cylinder head, as the combustion chamber shapes are very critical to flow—altering the cylinder head can unfavorably affect flow and power performance. FLOTEK's medium-sized 290cc oval port cylinder heads are designed for 3/8 in. pushrods with 0.120 in. wall thickness. They're available assembled or bare for a variety of engine applications. NOTE: This item is not sold as a pair; this is a single cylinder head.
