Could change the cam to a bit higher rpm but it's a street car mostly. By tune the carb you mean lean it out some more? Seems like it's in a decent range. I have an afr gauge in the dash. It idles a bit rich but WOT doesn't seem to bad
Maybe too late, but as far as the AFR goes, those numbers are ballpark. To find out the best AFR for your combo, yes you'll have to make some tests at the track or the dyno. I realize that's a PIA.
Go with a plan that involves one change at time. Be prepared to alter the follow up depending on results.
Idle should be a little rich. Certainly richer than stoich. As long as it comes off idle strong, no flat spots, its ballpark correct. If you want to start a different thread about the carb, we can dive deeper.
Hopefully, in spite of the side tracks, you got some helpful info about heads.
