That depends on what you wanna do and how often that engine is coming out. I just got the ARP bolts (your first link) and they're absolutely fine for leaving the engine in the car if ya need to remove the head. Using the studs (2nd link) are much better for the sake of torquing down and more easily lining up the head on the block, but the head doesn't come off there easy while the engine is in the car. You're required to pull the head straight up, and it doesn't quite clear to firewall. For serious racing, I'd say studs for sure. For the street, bolts work, but be sure to torque them more than factory spec. I torqued my bolts to 75ft/lbs. The choice is yours
