Retune my entire carb after installing new heads?

Do you still have anything constructive to add except to tell me it won't work?

I'm not running Pro Stock where I have to have every last hp on race fuel... It was working well at 10.3:1 on the old iron heads. Now it's around 10.6 (will have to look to make sure) with the new heads.

"Too low" is relative...street manners are decent, and I still haven't wrung it all the way out since there's no safe place around here to do it!
