Part No.: AR392

Price: $40

Description:

The AR392 side shields (batwings) provide a seal surface between the valley plate and the cylinder head when using a ported heads. The factory bathtub type gasket works just fine with unported heads but the bathtub gasket does not provide a good sealing surface when the heads are fully ported. Aftermarket heads such as the Trick Flow 240 heads require the intake gasket to be located precisely or else the intake flow will restricted. The AR392 side shields allow the intake gaskets to be positioned perfectly over the ports. Order AR397 for Max Wedge size ports.

Part No.: AR300A

Price: $200

Description:

AR300A is a 1/4 inch thick solid valley plate designed to work with Trick Flow 240 or other standard port type heads. This solid valley plate will only work when used with the AR392 “batwings” which provide a seal for the valley area. The AR300A is thinner than the two piece AR300 and does not have the machined access window. When using standard type cylinder heads the access window is not required since the valley plate can be removed without removing the heads. The solid valley plate can be drilled and tapped for a breather or a bung can be welded to the center for a hose fitting.
