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

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.

Perfect
Nerve racking to install but perfect

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.
