Saw you’d posted something on the Edelbrock forum, have you seen this posting?

Might also be worth thinking about checking balancer marks, vacuum leaks and possibly valve timing as well?
One last thing, that’s a fairly healthy engine you’ve got and I saw that your AFR was very high at 22.8 I’d recommend going at least another size larger on your fuel map to 5030 (as long as your O2 sensor is ok) and see how that works out, I can’t help thinking that it’s looking for more fuel.
