I run the Superformance gasket the problem is I can't tighten them enough..the 12 point is a good idea I'll try that thanks
Yes, the 12 point nuts are a good idea. You can also clearance the valve covers to get a socket in there, I'm sure there is plenty of meat to do it. Modifying a socket is another alternative but they are very hard and difficult to reduce in diameter.
Yes, the gasket performs best when there is proper clamp load applied
