Stainless Steel Oversize Intake Valve 28.5mm

This is the largest recommended intake valve when using the stock valve seat. The stock valve seat will need to be bored larger or a ARC#6148Y valve seat will need to be installed to take advantage of the bigger valve. This valve is top quality and has a radius-type keeper groove. Will fit stock valve guide. Use ARC#DJ-1046 or ARC#DJ-1047 HP valve spring retainers.
