Worth it
I've been building engines for years and I've had no problems with ARP hardware, ever. From 4 cylinders to v8s. I will always choose ARP for any of my performance builds. The price is worth it, buy once cry once. The quality of arp surpasses any other brand you can find. Cheap hardware can break, these won't.

You can never go wrong with arp head studs. Wether you are upgrading your engine for performance or just using them for added protection. They get the job done!

Will never go without
To the person that lubed and installed the studs then removed them and returned to Amazon.. You Suck! I live in the Midwest with no access to any local places to get performance products. I had these studs delivered on a Saturday only to open the box and find this. I inspected the studs and they looked like they were installed in the block but never had the head installed. I had no choice but to use these and Amazon gave me back some of the money I paid for them. Amazing product shame the buying experience was not better.

Mal empaquetado
Pedí la tornillería arp,En tiempos todo muy bien pero en el paquete llegó 10 espárragos,10 tuercas,9 arandelas y una pequeña tuerca qué ni al cazo. Me falta una arandela hubo un problema en el empaquetado.
