@pip-bip pretty much every modern car has an abundance of TTYs on it. The bolts themselves generally aren’t real stretch bolts though. It’s easy to tell when they are, they’ll have an unthreaded shank on them that shows visible deformation upon removal. I’ve never had a problem with reusing one either. The timing cover bolts are triple squares and the heads started to open up after reuse. Crank pulley bolt is probably fine to reuse, the engine mount bolts are really the first time I’ve noticed a difference in plasticity on reuse.
Using a non- stretch bolt is a pretty terrible idea IMO, they’re a pretty fine pitch and going into aluminum. I’m pretty confident that replacing those with non stretch would be not cost effective, moreover with the torque they see they’d likely tear out threads.
