This high-performance intake valve features a 2.125-inch head diameter with 11/32-inch (0.3415-inch) stem diameter and is designed to be 0.400 inches longer than stock height for applications requiring custom valve geometry.

Key Features:

  • Race Master straight stem design for maximum strength and reliability
  • Manufactured from premium NK-842 stainless steel for superior durability
  • Chrome stems and hardened valve tips for enhanced wear resistance
  • Swirl polished underhead areas and fully machined combustion faces

The straight stem Race Master design provides exceptional strength for demanding racing conditions. Recommended for use with Manley valve locks P/N 13098-16 (7-degree) or 13153-16 (10-degree) depending on your spring and retainer setup.

Great prices, filled and shipped immediately. Best deal around!

They have the best unbelievable prices and availability on all kinds of automotive products on the market and like I said the prices are great i will buy from here in the future

I pieced a roof rack setup from all over the internet, and Autoplicity consistently beat every other vendor on price and shipping, even most auctions on eBay!<br>I found the site confusing when searching for items directly (why was the "Roof Racks & Cargo Carriers" dropdown empty, when Google showed their ads for tons of these products?). Since they always came up at the top of a Google Shopping search for products, using their website's internal navigation wasn't ever necessary.<br>Customer service guy was a little snippy, but I could have just been interrupting his lunch.
