67 dart stroker hellcat gen3 hemi with twin turbos...

Very cool build!

I've got a few questions for you:
How much boost before heads lift? What can be done to keep em down? I've heard both bigger head studs and different material head studs.
What gaskets? I've seen the high dollar ones that incorporate o rings. What are the boost limits for the different gaskets?
What about o-ringing the block?

I'm really interested to know how much boost the Hemi can handle and stay sealed, and what mods up that number the most.

I know you've been keeping up with a lot of high end boost builds- figured you'd have the knowledge of what those guys have done to make it work.
