Now available, a set of eight X2 valves can be yours at the extraordinary value of $250 for a Small Block Chevy and you can take advantage of some professional valvetrain tutelage in the form of on-the-phone support from Marty Zimmerman.
Zimmerman is our X2 product manager and this valvetrain veteran has more than a quarter of a century of experience in the racing industry. In fact, his race resume includes work with a variety of engine and race teams, not the least of which is Evernham Motorsports at the NASCAR Sprint Cup level as a cylinder head professional.
X2 valves were born from Xceldyne, the leader in world-class racing valvetrain components with a successful NASCAR and Formula 1 heritage. So you get the best of both worlds with the purchase of X2 valves — quality valves and expert advice.
Our X2 stainless steel valves are available in a wide range of sizes. Most applications feature a choice of radius or square-lock groove. Additional features include a weight-saving dish design, laser-engraved valve face for easy ID and a swirl-polished profile. 
The X2 line incorporates X33 stainless steel with 35 percent alloy and a higher percentage of nickel. It also features X53 — a stainless steel with a variety of alloy elements that were targeted especially for intake valves.
And we use Inconel, nickel-chromium-based super-alloys designed specifically for exhaust applications that are oxidation- and corrosion-resistant materials well suited for service in extreme environments subjected to pressure and heat.
X2 delivers the tightest tolerances, finest materials and best finishes. Engine builders tell us everyday that they trust our Xceldyne valves to get them in victory lane. It’s that same heritage that went into the X2 line!
So if you’re looking for the best product, best advice and best price, give Marty Zimmerman a call at (888) 481-7269 and make the switch to X2.
