VAC Forged Stainless Steel Valves are precision made to exacting
specifications and are suitable for both street performance and
full Race vehicles.
They work great in street vehicles for day to day use where engine
build up and byproducts can harm typical "race valves", yet these
valves have proven their worth on max performance all out race
engines, surviving lap after lap, race after race, and even
multiple seasons without being replaced!
Our valves feature:
- One piece forged stainless steel design (compared to 2 piece
welded valves which typically fail at weld)
- Use of original 3 groove keepers/locks
- Flow optimized valve shape for improved power
- Lightweight engineering; enhance performance and increase valve
train component longevity
- Low-friction coated to preserve valve guide bore
- Enhanced resistance to fatigue from heat and high RPM
All of our M20 valve sets are sold with +1 mm oversized
diameter heads. This offers excelent flow improvements over the
standard valves.
-Intake Valves (6), 43mm
-Exhaust Valves (6), 37mm
VAC Tech Tips:
-These valves are a must-have when building a high performance and
very high revving engine: They dramatically reduce valve weight and
this improves valve train reliability greatly as the valve springs
and rockers do not have so much mass to control.
-Over-sized valves can help enhance maximum engine output.
