New head bolts got delivered today. Although, when I removed my old ones there were only two different types. This set came with three different types. x7 with the stud on top x5 shorter ones and x2 shorter ones with a nipple on top.

Will these work in my Jeep or should I return them and buy from a different manufacturer? If they will work which hole get's the one ones with the nipple?

Thanks!

 

The ones with the nipple and ones on the right look the same so if your old bolts did not have the nipple then you might as well consider the nipple ones and ones on the right the same.

 

Ya everything is the same except for the nipple, my only concern was clearance or what made them special, why not just include all the same oem style?

 

I believe the nipple ones hold and center the valve cover gasket. If you look at the valve cover gasket there are two holes in the center bands and those two nipples go in those holes.

 

I see what your saying. I have a reusable one that does NOT have those center holes, but a quick google showed me what you were referring to.

Thanks!
