Do I need to pull my valve cover again?

Need a picture of the top of 97 4.0 head
Anyone have a picture of the top of head/rocker assembly of a 97 Grand Cherokee? I put a new valve cover gasket on ( Fel Pro Permadry) with no issues... I thought.
While cleaning up I went to throw away the old gasket and realized it had two holes in it that the Fel Pro didn't have.

The holes are on the passenger side of the gasket on the flat steel strap that runs from left to right between the rocker assembly. I need to know if there is a hole in the top of the head where the holes are in the gasket, maybe an oil jacket or if it's something I dont need to worry about.

I believe they just help locate the gasket.

That's the worst feeling. That moment when you start thinking, Oh what have I screwed up now??!

Looks like I'm pulling the cover off again tomorrow. The holes I'm talking about are clearly shown on the gasket in the video before you even play it. I'm assuming I got one that never got those punches out. Oh well, live and learn. If they're needed I'm glad I haven't driven it more than down the street and back. Here goes another two hours of my life I'll never get back.

You don't have to remove your gasket again, it only goes on 1 WAY. The holes are ALIGNMENT DOWELS.

Why would you need to pull the valve cover if the gasket sits in its place like it should and you have no leaks? As was mentioned those holes are there just for alignment, and IIRC not all 4.0 cylinder heads even has those locator pins.

My 93 doesn't have them. Looking at the parts listing they were 96 and up only.

Alignment only.

If you are not leaking don't worry about it.
