Product Details

The Manley 12203B-8 is a high-performance titanium exhaust valve kit specifically engineered for Noonan Race Engineering (NRE) X1PM racing applications.

Key Specifications:

  • Head diameter: 1.900 inches
  • Overall length: 6.200 inches
  • Stem diameter: 0.3415 inches
  • Bead Loc keeper groove design

Premium Construction:

  • One-piece forged titanium construction with grain flow for maximum durability
  • Machined in state-of-the-art CNC turning centers to exacting tolerances
  • Premium titanium alloy optimized for exhaust applications
  • Ideal for high-RPM and extended high-RPM racing applications
  • Superior balance of hardness, ductility, and fatigue strength at elevated temperatures

Important Note: These valves do not include a hardened tip. Tip protection is required using Manley wear cap P/N 42104, 42104TM, or the Manley LocCap System. The "B" suffix indicates a Bead Loc keeper groove for secure retention. Designed for serious racing engines where weight reduction and reliability at extreme engine speeds are critical.

It was easy.

Length would have been perfect if it were 6 inches longer. Husband had to modify its path.

Quick, easy and free shipping. I'll be back!! Chris Wisconsin

Purchased a Dometic 16K AC retrofit unit to replace one that died after 20 years. Price for unit was comparable to other sites, and these other sites did not have the product in stock. Other sites were not specific on when part would be available. Boatplicity offered the best price for available stock. Part arrived as promised and delivery was on time. Arrived in excellent condition due to careful shipping packaging. AC unit has been installed and appears to be working well. Thanks for your assistance. Will use your site again for future purchases.
