Hey guys, have a 1090bs Big-sert kit for helping out with a head gasket job on the aluminum engines. I had an m52tu block that stripped the threads in the engine for the head bolts and this kit is the sh%* to put it bluntly. All of the inserts held great, so this is highly recommended if you are wanting to tackle the job. This kit comes with the drilling bit, the tap, the driver tool, thread locker, driver oil, alignment plate and alignment dowel. The kit will need more inserts which are very inexpensive on ebay. The inserts are 10x1.5x24.

Bought the kit for 445 shipped, asking 300.
