I picked up a Holley/Barry Grant 750 (conv. to 980 cfm) oh 15 years ago, and it's been sitting in boxes here and there ever since. I also have an Edelbrock 600 that's been sitting for maybe two years. It's a long-overdue question now, but what's the best way to preserve the gaskets and innards from decay/gunking up, and what can I do to prep them for re-use? Thanks, Eric.
