Not with me. I had a 2001 Duramax with the shiney heads and they were never a problem. I had the truck juuuust a little over 600hp for a while too.

That Dmax engine had 48 head bolts just like the Scorpion does so clamping should be fine.

I would say that unless you start feeding exotic fuels or just get crazy with power enhancements, the heads will be a lifetime part on this Scorpion engine.

I will say too that the aluminum head will transfer excess heat away from itself faster than iron would. That should be a good thing I think.

Time will tell.

I'm pretty sure the powerstroke only has 36 head bolts. They claim that it has 6 per cylinder, but the 2 bolts between each cylinder are shared by those 2 cylinders. I don't know about the duramax.
