RHS® Pro Elite™ 3.900" Bore LS7 Cylinder Heads not only get the best LS rectangular port heads onto all GM LS 5.7-6.0L blocks, they also provide up to 100 bolt-on horsepower over stock and feature all of the benefits of other RHS® LS7 heads. These cylinder heads fit all LS applications down to the stock 3.900" bore and utilize LS7 intake manifolds. Offered in both CNC-port and P-Port (unfinished runner) versions, the heads’ intake ports are raised .220" from the stock location for a straight line of sight into the cylinder, and utilize the LS 6-bolt head design compatible with both the RHS® LS Race Block and GM LSX Block. They can also be used with OEM, 4-bolt blocks. Additionally, a .750"- thick deck surface and reinforced rocker rails make for more rigidity in high horsepower and boosted applications. RHS® Pro Elite™ 3.900" Bore LS7 Cylinder Heads are designed to use eight standard, LS1-style exhaust rockers and eight offset LS3-style intake rockers and stands. Buyers will save money, as they won’t need to order a full set of less common 1.8 ratio LS7 rockers.
