The ARP 190-3609 Pontiac 400-455 EDE D-Port Head Bolt Kit is a comprehensive solution for those looking to upgrade or maintain their Pontiac engine. This kit includes a set of high-quality head bolts specifically designed for EDE (Early Dynamic Engine) D-Port heads, which were used in various Pontiac engines from 1964 to 1972.
Each bolt in this kit is made from ARP's proprietary 2000-series alloy, which is known for its exceptional strength and corrosion resistance. This material allows the bolts to withstand the high temperatures and pressures associated with internal combustion engines, ensuring reliable performance and longevity.
The ARP 190-3609 kit includes 12 head bolts, each with a 6-point hex head and a 3/8-inch drive. The bolts are threaded with an ARP2000 alloy 12-point SAE J1858/ASME B1.1 UNF-2b tapered thread. This thread design provides superior fatigue strength and sealing reliability compared to standard bolts.
The ARP 190-3609 kit also includes ARP's proprietary LockNut, which is designed to prevent the head bolts from loosening due to cylinder pressure. The LockNut is made from ARP's 2000-series alloy and features a unique design that provides a secure and permanent grip on the head bolt.
In addition, the kit includes ARP's high-temperature LockWasher, which is designed to prevent galling and provide a reliable seal. The LockWasher is made from ARP's 2000-series alloy and features a unique design that allows it to expand when tightened, providing a secure and permanent grip.
Overall, the ARP 190-3609 Pontiac 400-455 EDE D-Port Head Bolt Kit is a high-quality solution for those looking to upgrade or maintain their Pontiac engine. With its superior strength, corrosion resistance, and reliable sealing, this kit is a great investment for any Pontiac enthusiast.
