VT53702 120cc (472 / 500) and 425 2.19 / 1.85 Stainless Valves

120cc 2.19 / 1.85 Stainless Steel High Performance Valves

High quality 1-piece stainless steel 2.19″ intake and 1.85″ 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.

The 2.19″ intake valve is recommend for most builds. Some regular machine shops will tell you these valves won’t fit in the head – that is a sign you need to find a machine shop with more experience in non-stock machine work – fitting these valves is not a high-end operation.

These are the same valves found in our Super Street and Pro Street ported heads.
