FAQs

Q: What are valves? Why buy valves?
A: Valves are used to let a mixture of air and fuel into a cylinder and allow exhaust gases to get out. Each cylinder has at least two valves each, multi-valve engines have more, often four per cylinder. Upgraded head valves are able to withstand more heat from nitrous oxide use and turbo/supercharger use, so it's an excellent upgrade for people looking for added compression without sacrificing any reliability.

Q: How do you install valves?
A: Valves require headwork and should be left to the pros. While replacing valves, valve guides, retainers, valve springs and camshafts should all be considered for upgrades at the same time.
