DON'T USE BOLTS!
There's a reason they swapped from bolts to studs!!!!
When you wind them in and you tighten them, they are pulling on relatively weak aluminium, which destroys the threads, if you try and tighten a bolt, you'll usually end up pulling the threads out the cylinder head... With a stud you have a MUCH slimmer chance of pulling the threads out the head...
You'll NEVER get a manifold to seal properly with bolts, I've tried, you just end up wrecking the head...
Anything past D8B is usually studded, it's D8As that aren't normally... DHY, DHX, D8B are studded AFAIK...
