Would it be a good idea to make my hdl higher then my ldl? what possible side effects are there to higher hdl level then ldl?

Yes, but unlikely: Having an HDL higher than LDL conveys very low risk for heart and blood vessel disease. There would be no side effects to this condition. But this situation would likely be a genetic gift! It is difficult to raise your HDL; it is largely genetically fixed. Exercise, healthy fats, whole grains, omega-3's, normal weight, not smoking can help. No drugs at your age:)

Generally Yes: HDL and LDL are lipoprotein particles that affect risk of cardiovascular disease (CVD). Increased HDL particles are associated with lower CVD risk, while increased LDL particles are associated with higher CVD risk. In some cases high HDL choelsterol is not associated with low CVD risk. Testing for LDL and HDL particle number is often more predictive of CVD risk than LDL or HDL cholesterol levels.

That would be hard.: Just by the nature of their absolute values in the blood, it would be exceedingly difficult to make your HDL exceed your LDL. As long as your HDL is above 45, it's healthy; above 65 would be even better. It doesn't have to be higher than the LDL or the triglycerides for that matter.
