Well worth the money, a lot better than cheaper aftermarket â€œOE Equivalentâ€ head bolts, they do the job.
Head bolts are a solid product and were identical to OEM. I was very pleased with the speed of delivery, packaging, and the entire ZZP process. ZZP has also been very helpful with tech. information. It would be great if they could offer the Crank & Cam bolts as well.
