how bad are they? why take em out? just leave em in while you SODA BLAST the cases

only one looks pretty rough. but i'm just anal so if something doesnt look new it bothers me and comes out. also going to get some Ti head studs machined and PVD coated so figured i'd do engine studs at same time.

Soak in wd-40 and an 8 inch pipe wrench if you don't plan on reusing them.

youre obviously more experienced at this than I, so feel free to throw in your concerns.
shouldnt have to worry about the head trying to lift and stretching the lugs right? know that happens on racing vehicles, but figured wouldnt be an issue on a mx bike.
only neg i could see with Ti studs is that if you didnt coat them, they could possibly gall and never come out, but the PVD coating should stop that. and these things arent torqued super tight in the cases right? i mean, theres no clockwise, counter clockwise rotation like on a normal bolt that would try and loosen it. pretty much any force would try to pick it straight up. correct me if i'm wrong.
thx!

Just my 2 cents. Internet search for Ti head studs. I dont think you'll find any because in my understanding Ti is so stong because its somewhat malleable it gives some which would not be good in a bolt that you want to be more rigid if anything than what the factory designed.
If it was me , I'd send a sample of each stud to ARP & see if they dont have something that would cross, if that doesnt work just get new factory studs. Replacing the head studs is a good idea , case studs I'm sure wouldnt hurt either. If you do go the arp route please post on what you find
Motorrad might have even more enlightenment
