Cylinder head discussion 340 with stock above deck pistons

I do have adjustable shocks front and rear in the car. The tire size is 235 60 15 so they aren't big tires and I've been considering adding clatracks. That being said I haven't had tire shake or jump yet off the line. It just plants and I go. This season I will be setting my 2 step up so I can dial my launch rpm in better.
That tire size is plenty for a 340.
