Product Description
This valve seat is a custom part made by ARC to be used with our 28.5mm ARC#DJ-1122 Stainless valves. The inside diameter of this seat is .145" larger than the stock seat. Simply put, a bigger hole flows more than a smaller hole. Note that air cooled OHV engine heads get HOT and a tighter intereference fit will be necessary than what would be acceptable on a water cooled OHV or flathead engine. Valve Seat Dimensions: 1.035" ID x 1.213" OD x .218 HT.Product Videos
