Default 19# injectors or bigger?

Here are my current modifications:
cobra upper and lower intake
GT40 heads (off a 94 Cobra)
Hypertech superchip
Mac Underdrive pullies

I am planning on putting on a 65mm throttle body.

Should I stay with the stock 19# injectors or upgrade to the 24#... the car still has the SD setup (no mas air). I am not planning on converting to mas air, this car is just about to were I want it, I am not planning on anything wild with it.

suggestions?

Thanks

If you don't plan on going to a MAF system, stay with the 19s. The SD system won't respond very well to a change like that. Besides, the 24s may be overkill for your setup.
