Kooks LTH Install - Stage 8 Bolt Locking Clip Question

[RonBurgundy]

I’m installing the 1 7/8” Kooks LTHs. I opted to use the stage 8 bolts and locking clips that come with the headers instead of the OEM studs and nuts. You can’t use the OEM studs in certain spots because of clearance issues and my OCD wouldn’t let me mix match fasteners.

My question is how do you get the locking clips on the top manifold bolts? I was able to get them on all the bottom bolts relatively easy. I just can’t position my hands well enough to hold the lock plate in place while getting the locking clip in there.

My plan for now is to just run it with the locking clips off the top bolts. They’re all pretty easy to get to from the top of the engine, so I can tighten those as necessary. Has anyone had issues with stage 8 bolts without locking clips backing out or loosening?

I am planning the installation on my Kooks headers within a couple of weeks and could you take a snapshot of the locking clips that you mentioned in your notes so I can see what you meant.

Everyone that I’ve gotten responses from on other platforms said that they have seen zero issues using these bolts without the locking clips. Some of the people I talked to work in shops and install these often. They actually prefer to not use the clips.

Update: I removed the 8 sets of locking clips I was able to install and rechecked tightness on all 16 stage 8 bolts after a few heat cycles. I got maybe 5 degrees of movement out of a couple bolts, but nothing to call home about. I decided to just leave the locking clips off since the bolts stayed tight and they jiggle around and vibrate on the primaries. Not sure if it’s enough to cause false knock, but I’m not interested in finding out.
