Review on 🔩 Fel-Pro ES 71102 Cylinder Head Bolt Kit by Wayne Goff

My YJ 4.0 had 2 pins too many. at least they didn't match what PO put on the vehicle) and have 12 point heads (or whatever) prone to stripping. So that's a lower version of the hex heads that I removed. You will also need a special outlet for installation. I had to change them quickly to replace the head gasket on a specific day, so I got them. They seem to have got the job done, but I reused 2 old cylinder head bolts under the valve cover. I'm afraid it might not be as stable after removing it. Either way, the product does the job and looks very similar (if not exactly) to an OEM replacement. I would just prefer the upgraded hex head all things considered.
