Keith's street / strip motors are mild.
Find a shop that can tune the carb for you. In Memphis that will not be hard to do.
I think the motor will last for 10s of 1000 of miles for you on the street.
Biggest problem for card'ed motor is poor tuned carbs that wash down the cylinder walls, speeding up ring wear and contaminating the
oil.
You can always call Keith and talk to him or one of the guys in the back that build motors.
I see you live in Memphis about 3 hours west of Florence, Al.
We have an active group of Cobra in North Ala and Tenn. Maybe you can join us sometime. We have a few injected Cobras and lot of carb'ed ones. Coach Mike is our carb tuning guy.
