Well, I got the full report on it today first hand. #7 is where it started and it migrated to #1...

The total damage is one head is toast, block now needs an overbore, crank needs turned, two pistons are complete toast, valve spring seats/retainers were beat to heck....I never killed one this bad. Looks like it will have a rev limiter next time out.
