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.

Better then OEM
These are the best way to go when doing a cylinder head job. Far exceeds even factory OEM bolts.

D16Y8
Installed on my turbo 96 civic with a D16Y8. Product came well packaged and all parts there. Some have said theirs was opened / installed before, Mine was sealed with plastic wrap and nothing was missing / opened. Install is super easy. 4mm allen for the top of the stud for install and a 12mm 12pt socket for torquing down the nuts.

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.
