Small Block Chevy LS-1 / LS-2 (LS-6 Heads) Race Flo Intake Valves - Set of 8 by Manley Performance
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 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.
Engine builders successfully using EV-8 alloy (21-4N) valves will find this series of Manley valves to be an excellent product at a very attractive price. The ultimate tensile strength tables on this and the next page show that the Manley Race series is equal to the best offered by competitors.

Before Ordering
〇 About Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
All product databases are based on North American vehicles (USDM). Please confirm whether the product can be installed on a Japanese 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 investigate for you.)
If you order without verifying 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. 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 checkout. Shipping estimates are 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.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes about 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air freight; they are not shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products handled by our company are basically designed and manufactured outside of Japan. Please note that they do not conform to the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. 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 box or the product. For products with shipping damage, defective products, or items different from your order, we will only handle returns, refunds, or exchanges if you contact us within 7 days of receipt. Please understand that for products sold through us, we will only handle warranty-related matters "through our company." Please note that we do not handle matters through other companies or distributors located within Japan.
