Gain plenum volume, improve cylinder balance, and make your Hi ram manifold look better! We offer these tops in 3 different heights. Our standard tall model is 6.5", the mid height is 5", and the low profile comes in at only 2.75". These all include a vacuum block on the rear that feature two 1/8" npt and one 3/8" npt female ports.
These are built once the order placed.
