Have used these bolts 10x’s now building LS engines with cam/head swap and would not go any other way. Simple torque specs 25-50-80 ft lbs. reusable and unprecedented quality. Dont forget to run a cleaner tap through all your holes to clean out the old sealer. Def a must

Good head bolts! I always replace stock bolts with ARP whenever I have the opportunity. I got these head bolts for a Pontiac G8 with the LS3 block and heads. I chased the bolt holes with the old bolts and these ARP bolts installed perfectly. You can't go wrong buying these! Don't mess with the factory TTY bolts either, the last thing you need is a broken head bolt!

ARP has always been known to make great installation hardware and they didn't miss on this either. High quality and fit the bill.

I used these for my LS7. They worked great with no issues. Make sure you read and follow the directions. Lay out and arrange all the pieces for final assembly to save a lot of time.

I rarely leave a review, but in this case I feel it is necessary. Over the last 20 years of building engines, I have and always will use ARP fasteners. They have been the only manufacturer I turn to for all our builds. Today, I had the first failure. A head bolt sheared off in the block. What was an almost complete build, is now back to parade rest. We always use ARP's guidance for install, and never go beyond the tried and true specs. We are assuming the failure to be a material issue. Just a reminder that even though they are the go to source, nothing is guaranteed in this business. Hopefully, the machine shop can remove the broken bolt. If not, it's a wasted LS block.
