Incorrectly machined cylinder heads, blocks and intake manifolds or any combination thereof can cause intake leaks. Discover these potential problems before you machine or assemble with the Intake Angle Gauge.

These precision-machined gauges are made for checking the block and heads assembled together as well as the bottom side of the intake manifold for incorrect included angles. Simply set the gauge onto the intake runners of the heads installed on the block or against the intake runners on the bottom side of the intake manifold and check for an air-gap either visually or with a feeler gauge.

Manufactured from aluminum alloy and hard anodized for durability these gauges are available for three different head/ block applications.
