Default IAC-Valve problem, Need help

Just got my car running, but now i have an issue. I have an Edelbrock Intake Manifold, & i found a coolant leak where the IACV meets the In.Manifold. The 2-Bolt holes are stripped-out. Which is also causing a HUGE vacuum-leak also

What should i do?

Use the next size bigger bolts & re-thread the holes?

Is deleting the IACV an option? I know some people are opposed to this.

No, however I don't run a/c or heat or stereo or anything because mine is raced out. I wouldn't do it if you were running a big stereo or anything that draws excessive power. The IACV just adjusts idle to accomodate(sp?) extra power usage. Otherwise the rpm's would drop a little when using power. The IACV eliminates this.

It may not be an option for you if it's just a grocery getter, but it is possible.
