Small Block Chevy LS-1 / LS-2 (LS-6 Head) Race Flo Intake Valve - Single by Manley Performance
The Pro Flo version, identified as Race Master and Race Flo valves, are manufactured with XH-426 material for exhaust and NK-842 material for intake. This series of valves is intended for bracket, drag, and oval track racers operating at 8000 rpm or less. Generally, engine speeds above 8000 rpm require titanium valves.
Any engine builder successfully using EV-8 alloy (21-4N) valves will find this series of Manley valves to be an excellent product at the most attractive price. The ultimate tensile strength tables on this and the next page demonstrate that the Manley Race series is equal to the best offered by the competition.

Before placing your order
〇 About import consumption tax
At Shaft-ya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount you pay at checkout.
〇 Checking compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether or not they can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding delivery
Shipping costs are paid at the time of payment. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the automatic shipping calculation may rarely differ significantly from the actual shipping cost. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please place your order with time to spare. If you are in a hurry, please contact us in advance to confirm delivery times. Furthermore, all products are transported by air. They are not shipped by sea.
○ Regarding compliance with Japanese vehicle inspection (Shaken)
All products we handle are basically designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese vehicle inspection system" in any way, and we cannot provide strength calculation documents or similar for that purpose. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding warranty
Please check the contents immediately when the product arrives. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product. Please understand that we will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or products different from what you ordered. Please also note that for products sold through us, warranty-related support will be provided "only through us." We do not provide support through other companies or distributors located within Japan.
