Please take a look at the attached picture. Note the arrow pointing to a empty bolt hole located in the left cylinder head. Should there be a bolt here? I've been working on the car over serveral weekends and I can't recall if a bolt was installed or not.

Any help would be appreciated.

Don't worry about that. Looks like a extra hole in the head used for a different configuration.

IIRC, That bolt hole will be plugged with a bolt from the ICM bracket.

On the n/a engine, that bolt hole remains empty.

Thanks Andy.

Thanks for everyone'* help.
