Manley Race Valves and WOT-Tech updates
 

I have listed the Manley Race valves for the 3400 engines. These are best for boost and high RPM application, especially those looking to use the available XFI cam lobes and the PAC 1518 springs.


Stainless Steel XH-426 Exhaust and NK-842 Intake valves
Chrome Stems and Hard Tips
Swirl Polished and Fully Machined
Race Master Exhaust (Straight Stem) and Race Flow Intake
Recommended exhaust valve for Alcohol Engines
Designed for up to 8000 RPM and 1200 Degree F temps

These are optional on the street/strip 3400 heads and standard on the race/boost 3400 heads.

On a mild build, with a street RPM probably 6500 RPM's or less, would you suggest these or stick with the 3500 valves

3500 valves. These are excellent valves meant for an aggressive cam with the PAC 1518 springs, or a lot of boost. The 3500 valves are the best option for anything else, stock, mild, even 6500 with a cam that has moderate lifter acceleration.

^^ Cool that's what I'm looking to buy.

I don't want my car to be an all out race car :eek:
