Nope.
Manufacturer and model determines the torque value.

Edit in:
I know you’re from another country and this will probably be expensive to get there, but I’m willing to bet most of us would say to get ARP head bolts for a supercharged 502.

Share a pic of your bolts, just in case you may have these.
