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

Share

Memphis, TN – New RHS® Pro Elite™ 307cc Big Port LS7 CNC-Ported Cylinder Heads are designed for bigger 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. RHS® Big Port LS7 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. Intake ports are raised .220" from the stock location for a straight line of sight into the cylinder. The heads also feature a .750"-thick deck surface and reinforced rocker rails, which make them perfect for high horsepower and boosted applications. They work well with all existing LS7 parts, but have bigger intake ports and valves than the standard RHS® Pro Elite™ LS7 Cylinder Heads. They feature the popular 6-bolt head design, making them compatible with the RHS® LS Race Block, GM LSX Block and OEM GM LS blocks. These aluminum, CNC-ported 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. RHS® Pro Elite™ 307cc Big Port LS7 CNC-Ported Cylinder Heads are designed for larger cubic inch, all-out race engines, but are also ideal for 454-502c.i. LS street engines.
