VT53701 120cc (472 / 500) and 425 2.11 / 1.77 Stainless Valves

120cc 2.11 / 1.77 Stainless Steel High Performance Valves

High quality 1-piece stainless steel 2.11″ intake and 1.77″ exhaust valves for 120cc heads (’74-’76, casting numbers ending in 493 or 552) and 425 heads (’77-’79, casting numbers ending in 423 or 112).

They are the correct length to achieve the stock valve stem height in 120cc and 425 cylinder heads with optimal seat placement in the chamber. They feature a 45* valve seat and 11/32″ (stock diameter) valve stem.

These are the easiest valves to install. They are primarily used in applications where an individual wants to cut the seats themselves or does not have access to a machine shop that can handle the job of cutting the seats for the larger valves.
