Product Description
Interstate-McBee M-3283337 Head Gasket, .010" Oversize – 1989–1998 5.9L Cummins 12-Valve
.010" oversize (thicker) head gasket for the 1989–1998 Dodge Ram 2500/3500 with the 5.9L Cummins 12-valve (6BT). The increased thickness helps maintain proper piston-to-head clearance after block/head resurfacing or when piston protrusion is on the high side of spec. Sold individually.
- .010" oversize thickness: Compensates for machining and protrusion variance.
- Engineered fit: Matches Cummins reference 3283337 application for 12-valve 6BT.
- Reliable seal: Built for stock to mild performance levels when installed per OEM procedure.
- Direct replacement: Drops into the OE location with factory dowels and coolant/oil passages.

FAQ
What does “.010" oversize” mean?
It’s a thicker-than-standard gasket (by ~0.010") used to maintain proper compression and clearance after resurfacing or when piston protrusion requires additional thickness.
How do I know if I need .010"?
Measure piston protrusion and compare to the Cummins specification chart. Choose the gasket thickness that keeps the assembled clearance in spec.
Do I need new head bolts?
We recommend new OE bolts or a quality stud kit. Torque-to-yield bolts should not be reused. Follow the fastener maker’s instructions.
