Random bolts and thick washers from Ly-con???

Hey Guys!

I’m hoping people on here smarter than myself can help me out with a question.
I got my cylinders back from Lycon after a port in polish. In a bag with miscellaneous parts (i.e. fuel injectors, spark plug adapters, etc) were three 3/16 bolts and two thick washers (see pics). I can’t for the life of me figure out where they came from???? Anyone recognize these? Engine is a superior XP IO360.

You’re right my mistake. They are 1/4-20s. They were just in the bag. I guess I’ll call Lycon and ask them no reason to have case bolts in this bag as I just sent all 4 cylinders.

many 1/4-20 bolts on that engine for things other than the case seam.
 
Per Ken at Lycon They are 520 rocker arm bolts. Not sure how I ended up with them.
Anyway thx for the help!
