Que puedo decir son arp

Remember not to over torque and strip your heads threads.

Great price and product thanks

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

Worked great.

Top quality, nice washers to distribute the force, secured kooks headers to my cts-v. longer and overall better looking bolt than the cheap kit used previously. If I have to remove the headers in 10 years my hope is these back out nice and easy, and ARP is the name for that.

seem to be quality.

Can’t beat arp
