I may be over worrying... but I just want to run it by you folks first. Today I was showing a friend my work that I had been doing on my engine and I showed him the cam chain guide mod. He noticed something I did not. In my pictures he said my lock nuts may not be locking because my screws end just shy of the end. I used Red loctite and cranked these suckers down. Is my friend right? Is there not enough space for these to not have locked down? I already buttoned up my engine... but if this seems like a safety concern. I am more than willing to make it right. What do you guys think.
