Common stainless bolts are generally not as strong as grade 8, but about as strong as Grade 5. 18-8 is the alloy (304), not grade (18% Cr and 8% Ni). There are some stainless steels that are very strong. ARP sells bolts that exceeed Grade 8 at 170,000 PSI strength. They are precipitation hardened 17-4 alloy.
Be careful where you use stainless bolts, and what type you use.
