The stock bolts kept breaking in the cylinder heads and got a new set of heads. These were the first on my list of things to get and couldn't be more happier with a set of ARP bolts. Just make sure you put plenty of ati seize lubricant on them.

Bolts appear to be manufactured to high quality standards. All threads were perfect and corrosion finish was flawless. Torqued to specifications during install without issue. Used to replace the OEM bolts on my 2013 Escalade with the 6.2L as one had broken off in the block, which is a very common defect for this line of GM motors. Only time will tell if they hold up under Northeast conditions better than the OEM bolts did.

Just installed a set in my '02 Sierra Z71 with a 5.3l LM7 and factory cast iron manifolds. The threat depth, with supplied washers, is same as factory fasteners. Perfect fit.
