VAC Severe Duty Valve sets are precision made to our exacting
specifications.
Intake valves are Forged Stainless Steel, while the exhaust
valves are a Severe Duty Alloy. This set is built for super high
horsepower, forced induction, or Nitrous Oxide equipped S14s that
generate very high combustion temps. Made from a highly
advanced alloy (similar to manufacture name 'Inconel'), our valves
will survive where no others will.
If you are shooting for ultra high HP/ High boost we have the
valves for you!
Our valves feature:
- One piece high tech alloy construction for maximum heat
resistance(compared to 2 piece valves which fail at weld, and melt
at high boost)
- Single (1) groove keeper style for maximum deformation and heat
related failure resistance
- Extreme heavy duty; if these don't survive nothing will
- Tested to 9500RPMs
- Valve sets are oversized; in:+2, ex: +1.5; optimum for high
horsepower applications
VAC Tech Tip:
These valves are built for high heat and severe duty. With our
valve springs they should prove exceptionally reliable. For
naturally aspirated, high revving applications, we recomend our
forged stainless steel valves as they are lighter.

valves. Valve set includes Forged Stainless intake, Severe Alloy
exhaust
