Review on Enhance Engine Performance with Fel-Pro ES 72390 Cylinder Head Bolt Set by Ken Barnett

Don't take this. Get OEM. Put all the screws in and started tightening them and the second screw broke 2" (had to be drilled and removed with a simple, long and tedious operation). The other screw I removed after this one broke was very thin and probably broke shortly after tightening. All of the tightened bolts were within specification, which was very worrying for a company with such a solid reputation.
