Product Details

The Manley 11793-4 Race Master exhaust valve set is engineered specifically for Ford 2.3L engines with Esslinger heads, delivering exceptional performance for bracket racing, drag racing, and oval track applications operating under 8000 RPM. This set includes four precision-manufactured exhaust valves designed for flat tappet camshaft compatibility.

Specifications:

  • Valve head diameter: 1.590 inches
  • Valve stem diameter: 0.342 inches (8.67mm)
  • Overall valve length: 4.800 inches
  • Material: XH-426 stainless steel construction
  • Valve head style: 9 degree dish
  • Lock groove: Single-groove conventional style (uses 7 degree keeper, not OE Ford 3-groove)
  • Seat width: 0.100 inches
  • Tip length: 0.550 inches
  • Weight: Approximately 104 grams per valve

Premium Features:

  • Chrome stems for enhanced wear resistance and durability
  • Hardened valve tips to withstand high-stress racing conditions
  • Swirl-polished underhead areas for optimized airflow
  • Fully machined combustion faces for maximum efficiency
  • Race Master straight stem design for reliable performance

These Race Series valves are constructed from high-quality stainless steel and undergo rigorous quality control to meet the demanding requirements of competitive racing. Each valve is swirl polished and fully machined to deliver consistent performance and superior airflow characteristics.

Note: This aftermarket valve uses a 7 degree single-groove keeper system and does not utilize the original Ford 3-groove keeper. Designed for racing and off-road use on flat tappet applications.

Awesome love the site

Over all the order was very easy to place and shipping was very fast. The only problems that I had with the web sit was there is no phone contact for questions about parts and there was no list of what was included with parts kit.

Excellent all the way around!!! I'll never waste time again with the frustration of shopping around only to find an inefficient web site or long shipping delays. I've been in the auto repair industry for 35 years. I highly recommend AUTOPLICITY.

fast shipping great deal

Best price for Hummingbird mapping products. Exactly as advertised.

product just as described, received in 3 days

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Done

Great prices will shop here again.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.
