Head Bolt Kit

I used this on a big block setup, and the hardware felt right for the job. The weight is what I would expect from real engine fasteners, and the material feels strong and properly machined rather than lightweight or questionable. The 12-point heads are clean, and the fit was solid during installation.This is not the kind of part where I want to gamble on poor quality, and these felt consistent from bolt to bolt. The versatility is good across the listed older big block applications, but I still checked fitment carefully before using them because engine parts are not something to guess on. Installation was straightforward, and the instructions/spec information were clear enough to follow with normal engine assembly procedures.The durability is the main reason I like them. They feel like they are made to hold torque properly, and the finish looked clean out of the package. The value is good compared with piecing together questionable hardware, especially when doing a repair or build where dependable fasteners matter. I would use them again.

A fantastic set of head bolts. These are absolutely a MUST HAVE if you are replacing the blown headgaskets in your Motor Home RV. They fit the 454 big block chevrolet engine and are superior to the stock bolts in every way.The bolt kit, it is a good deal for an actual name branded set of bolts, much more reasonable that the A rp bolts.I have no complaints or issues with these bolts at all.One tip for the engine builder: These are stock replacement style bolts, if you are upgrading to Pro Comp or aftermarket aluminum heads they may require special application specific bolts. I know my imported Aluminum heads that I used on a previous engine required those bolts, the stock ones were not long enough.
