FAQ

Q1: Are these valves sold individually or as a set?
A: This listing is for a matched set of one intake valve (145-7390) and one exhaust valve (147-8211). They are typically replaced per cylinder as a pair during an overhaul. Quantities can be scaled for multi-cylinder engine rebuilds.

Q2: Do I need to machine the valve seats when installing these new valves?
A: Yes, it is highly recommended. For optimal performance and longevity, always cut or re-face the valve seats in the cylinder head to ensure a perfect seal with the new valve’s machined face. Installing new valves on worn seats will lead to rapid failure.

Q3: What is the lead time for shipping to [Europe/Middle East/Asia]?
A: Lead times vary by destination and shipping method. For standard sea freight to major European ports, expect 25-35 days. Air freight to global hubs can reduce transit to 5-10 business days. Contact our sales team with your destination port for a precise shipping quote and timeline.
