Small Block Chevy Race Master Intake Valves - Manley Performance Set of 8
The Race Master, and the Pro Flo version identified as Race Flo valves, are manufactured from XH-426 material for exhaust and NK-842 material for intake. This valve series is intended for bracket, drag, and oval track racers operating at 8000 rpm or less. Generally, engine speeds above 8000 rpm require titanium valves.
Engine builders who have successfully used EV-8 alloy (21-4N) valves will find this series of Manley valves to be an excellent product at a most attractive price. The ultimate tensile strength charts on this and the following pages show that the Manley Race series is equal to the best offered by the competition.

Before placing your order
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred upon import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇 Compatibility Confirmation
Our entire product database is based on North American specification vehicles (USDM), so please confirm whether the product can be installed on a Japanese specification vehicle (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 be happy to look into it for you.)
If you 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 the Japanese model of the vehicle 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 fees are paid at the time of checkout. For shipping estimates, the cost will be calculated automatically 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 fee and the actual cost. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic delivery in Japan, international delivery takes approximately 7 to 14 days, so please allow plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are transported by air. They are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
In principle, all products we handle are designed and manufactured outside of Japan. Please understand that they do not comply with the "Japanese vehicle inspection system," and we cannot provide documents such as strength calculation reports for Japanese vehicle inspections. Therefore, all parts are sold for use on "circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. We will only accept returns, refunds, or replacements for products with shipping damage, defective products, or products different from what was ordered if you contact us within 7 days of receipt. Please understand that for products sold through us, warranty support will be handled "exclusively through us." We do not handle warranty support through other companies or distributors located within Japan.
