i have to say with stock cam and heads, its not gonna happen unless you gut the car out some.
i'd say you need at least a cam with those heads to have a chance if you have the right gearing and converter and on slicks.
with stock cam and upgraded TPI/ or other intake with those heads and right gearing/converter could possibly hit lower 13's
