RHS Pro Elite™ LS7 CNC-Machined 307cc Big Port Cylinder Heads

Memphis, TN – New RHS Pro Elite™ LS7 CNC-Machined 307cc Big Port Cylinder Heads are designed for 454-502c.i. street engines that require additional runner volume and air flow to support the large cubic inch design.

Big engines make big power, but often cylinder heads don’t provide the necessary flow characteristics for large power plants. New RHS Pro Elite™ LS7 Big Port Cylinder Heads solve this problem. They are the only raised runner aftermarket LS7 heads with the runner volume to support large cubic inch applications, yet are still able to utilize both production and aftermarket intake manifolds and valve trains. The heads work well with all existing LS7 parts, but have a bigger intake port size and valve than the standard RHS Pro Elite™ LS7 Cylinder Heads. These aluminum, CNC-machined heads feature a 307cc intake runner, 98cc exhaust runner and 69cc chamber volume. The intake valve is 2.250″ x 5/16,” while the exhaust valve is 1.615″ x 8mm. Designed for 454-502c.i. street engines, RHS Pro Elite™ LS7 Big Port Cylinder Heads are also ideal for smaller cubic inch, all-out race engines.
