VAC Stainless Steel Valves give you the
advantage
VAC Forged Stainless Steel Valves are precision made to exacting
specifications and are suitable for street performance, or full
Race vehicles.
They even 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 Plus-One Millimeter (+1) valves feature inconell exhaust
construction to withstand high HP from large cams and aggressive
race builds, or big power FI setups.
Our valves feature:
- One piece forged stainless steel design (compared to 2 piece
welded valves which typically fail at weld)
- Use of single-groove keepers (locks) as is popular with
racers
- 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
We offer:
Groove Type- ALL are Single Groove as preferred for
S54 race engines. REQUIRES use of single groove race valve locks
offered below.
Valve Sizes- OE size if for use with VANOS equiped
engines, for serious high-power race builds, +1 oversized is
available for race engines with VANOS eliminated
VAC Tech Tips:
-These valves dramatically reduce valve weight and this improves
valve train reliability greatly as the valve springs do not have so
much mass to control.
-Oversized valves can help enhance maximum engine output.
-Must be used with single-groove 6mm valve locks / keepers
