Nice product. Fit well
Nice product. Fit well. Washers are molded into the head of the bolt and not free like the OEM. Make sure you put some grease or oil under the bolt head before torqueing them so you get an accurate torque and don't mess up the aluminum head.

New design
The first set was packed wrong from Fel-Pro. They packed 2 different sized bolts. It was returned and the new set was correct. I reached out to Fel-Pro and they really didn’t believe that it could happen. Amazon made it right though. Good bolts overall.

These are better than OEM head bolts!
These work great and have larger head diameter than OEM which gives them more clamping force .

Bolts in box looked used
The box looked unopened and was clean on the outside the grease on the box is from me after handling the bolt bags, getting grease on my fingers. You can see the bags look like a perforated seal was removed. The edge of the flats looks like they have been in contact with a socket. I just sent them back and reordered from a different manufacturer that has washers on the bolts like the OEM bolts for a little more money.
