Customers find these engine cylinder head bolts to be of good quality, working well without breaking, and appreciate that they come with sealant already on the threads. The product fits correctly and offers good value for money, with one customer noting that the smaller head makes torquing easier. However, durability receives mixed feedback, with several customers reporting that they break off in the block during installation.
