If you're planning to build your 350z engine make sure to add performance valves. The performances valves will give your Z the extra power it needed for every day tuner. Premium quality racing vales are perfect for high rpm performance engines. Performance valves compare favorable with top of the line models from competitors in appearance and performance. Applications for aftermarket heads start at 0.050 longer. The performance valves are fully swirl polished, and have chromed stems and stellite tips. Performance Valves special thick margins and modified radius allow for best flow and make the valves much lighter. Performance Valves is for Pro Street and Racing are engineered for High RPM and High HP. Performance Valves outperform the shock valve on the market today, and with their Nitride Coating are perfect for High Temperatures and run cooler which improves value life, Nitrous, Turbos and Superchargers. For naturally aspirated motors these valves will give you a much greater cylinder flow for good HP gains. The micro hardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitride layer. Performance valves surface finish is smoother than with chromed stems, having less friction between stem and guide. Performance Valves seat surface is harder with the nitride layer, lasting longer with lead free fuels, alcohols, nitro or other explosive mixes. Matches any kind of seats nodular iron seats, steel powder metal seats, hard aluminum copper seats or beryllium copper seats. The higher the engine speed the bigger the power loss due to internal engine friction. The black nitride layer reduces this power loss due to less valve-guide friction. The nitride layer is adhered to the base material at a microscopic level, so does not flake or brake when the valves bend due to impacts with the pistons. The Black Nitride applies to the whole valve while the chrome coating is only applied to the stem. Performance valves are swirl polished, have stem undercut and a hardened tip.
