Small Block Chevy Race-Flo Intake Valves - Set of 8 by Manley Performance
Race Master, and those identified as Pro Flo versions, Race Flo valves are manufactured from XH-426 material. NK-842 is used for the exhaust and NK-842 for the intake. This series of valves is intended for bracket, drag, and oval track racers. Under 8000 rpm - at higher engine speeds, titanium valves are usually mandatory.
For engine builders using these under normal conditions, EV-8 alloy (21-4N) valves are found in this Manley series. The valves offer an excellent product at a very attractive price. The ultimate tensile strength table on this and the next page demonstrates that the Manley Race Series is equal to the best ever offered by competitors.

Before Ordering
〇 About Import Taxes
At Shaftoya Shopping Site, we cover the import taxes incurred during import, so there are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Since all product databases are based on North American vehicles (USDM), please confirm compatibility with 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 check for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items 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. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of settlement. An estimate of shipping costs is automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international shipping takes about 7 to 14 days, so please 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 freight.
○ Regarding Japanese Vehicle Inspection Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength calculation documents for Japanese vehicle inspections. Therefore, all parts are sold for the purpose of "use on circuits, private property, and off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival of the product. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product. We will handle returns, refunds, or replacements only if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or products different from what you ordered. Please understand that for products sold through us, warranty-related correspondence will be handled "only through us." Please note that we do not handle correspondence through other companies or distributors located in Japan.
