ARP Chevy LS 3/8in Flange Hex Header Bolt Kit

Installed on an 09 G8 GT, fit perfect, and of course stellar quality. Perfect for anyone doing headers or replacing factory manifold bolts on LS based blocks. It’s also a lot more convenient and easier to use a 10mm wrench in the spaces since the head is smaller on these. With them being smaller it even stopped the bolt from contacting the spark plug heat shield

Do it right the first time with these Bolts! Best around in fit, finish, quality! Spend the money on the right part for your application!

ARP is a great company, with great products!!

Great product

Description misleading, my headers require 3/8 -16 thread, description describes 3/8 flange not thread size

had to replace the header gaskets so decided to go with new bolts while theyre off. I have always used ARP in all my cars. No problem whatsoever and like always a perfect fit. 2010 Camaro SS LS3
