Highest Quality INTAKE & EXHAUST VALVES
CLARK valves are made by an ISO9001 certified manufacturer using the newest alloys to run safely with no lead gas at
the higher temperatures of Corvalr engines. Head shape and all size specs were taken directly from “NOS” valves. The
stems are held to .0005 of specs and the faces are cut with precision CNC machinery and checked with laser during
production. The exhaust valves are made from a high nickel (JIS alloy) stainless. Good for 1600–1800 degrees. The end
of the exhaust valves are “tip welded”. This puts a softer material at the very end to reduce rocker arm wear.
REAL TURBO VALVES Same material and technology as used in todays Turbo engines plus they are
TUFFTRIDED.
TUFFTRIDING – A high performance dark surface hardening treatment which aids “oil retention” and yields
100,000+ miles with greatly decreased valve stem wear & guide wear. ALL CLARK VALVES listed are Tufftrided.
Individually Wrapped – Since these valves are custom produced just for us, we requested individual protective
packaging – another small but important detail.

Why get NEW VALVES? My Machine Shop can just regrind!
There are several advantages to our NEW VALVES. The main ones being that they are made from superior materials
to exacting specs and also available tufftrided. You should also consider that your valve seats are probably going to be ground. Do you also want to grind the
valves, making for a thinner valve head on a valve that may be 30 years old? Also, most Shops CANNOT grind the valves as accurately as a valve factory.
Why Replace GUIDES? The valve stem can wear and the inside of the guides can wear. As one or both wear it allows the valve to “lash” around,
causing even faster wear but even worse, not allowing the valve head to fall squarely on the valve seat. This leads to rapid wear on the face of the valve, valve
seat and may cause the seat to loosen.
CONNECTING ROD BOLTS – In 2001 GM doubled our cost on rod bolts and tripled the cost of rod nuts! We have found an excellent
replacement bolt and heavy duty nut. Replace those fatigued bolts and nuts.
Important Notes!
1. The NEW STYLE BOLT & NUT – are 3 grams heavier than the stock. We agree with Larry Claypool that this should have no affect but we both also
SUGGEST they NOT BE MIXED on the same rod and If you put them on one rod you should also put them on the “opposing” rod.
