VT51702 76cc 2.25 / 1.90 Stainless Valves

76cc 2.25 / 1.90 Stainless Steel Racing Valves

High quality 1-piece stainless steel 2.25″ intake and 1.90″ exhaust valves for 76cc heads (’68-’73, casting numbers ending in 250, 950, or 902).

Factory 76cc heads came with valves that were not hardened for unleaded fuels. While they are tougher than than the pre-unleaded valves found in lesser engines, it is still possible to burn a valve. These replacement valves eliminate that potential issue. They are the correct length to achieve the stock valve stem height in 76cc cylinder heads with optimal seat placement in the chamber. They feature a 45* valve seat and 11/32″ (stock diameter) valve stem.

The 2.25″ intake valve is recommend for professional fully-ported heads only, and are generally used for competition and very high end street applications, where aluminum heads are not practical for one reason or another, or not allowed. Many regular machine shops will tell you these valves won’t fit in the head – that is a sign you need to find a cylinder head shop with more experience in high performance applications if you want to use these valves. For the more ‘normal’ oversize valves, we recommend our 2.19 / 1.90 valves.

These are the same valves found in our ProComp 76cc ported heads.
