Ductile Iron Valve Seals, Exhaust

To suit Aftermarket Aluminum Heads, Exhaust

Original Application- Brodix

This listing is for a set of eight ductile Iron exhaust valve seats. These have a 3/8" depth intended for use in aftermarket aluminum heads.

        Specifications:

• OD: 1.650" (Actual)
• ID: 1.350"
• Depth: .375"
• Quantity included in purchase: Eight

These seats have an "actual" outside diameter of 1.650", added press fit is not included like common fractional size seats.

The valve seat counter-bore in the head needs to be machined smaller to establish the desired press fit.

Example: a 1.643" counter bore would provide .007" press fit. Machine the counter bore to provide the desired press fit.

Adjustable valve seat cutters are normally required to fit this type of seat.

Limited quantity is available, this item is not refundable- be sure fitment is what you want before ordering.

Thank you-
