you hit the nail on the head! extra bolts are needed badly! :hammerhea
I think I am switching to a Merlin block and heads so I should be okay.
but I don't think I will be boosting that much anymore.

And the valves hit the piston. Nice full contact area tho.

Yeah, that was caused by the cam bolts shearing off at the shift. It's cool going fast, but you tend to break more crap. At least I broke into the 6's ... 6.95 @ 157
Valve job now needed as well ...
