Default Problem LS3 int & milled LS3 heads

To put it simple, you may have seen my dyno run post. But we found bank 1 running leaner than bank 2. So in short there is a small manifold leak. The ONLY place it could be leaking is the intake. Heads were milled .030 and intake didn't fit flush on the bottom. I thought it was close enough to seal but it isn't. Going to try to find thicker gaskets or something...

Thanks but I sill have the fast bolts on there. Going to see if I can find some thicker gaskets. Note the intake is new and the alignment pin was cut off since it was also holding it up.
