I like the stock height but the front needs to sit level could I just block it up or would that be stupid?
NO! I speak for the safety of everyone on the road around you, and the law.
Not every state, but most states have laws on the books prohibiting lift blocks on the front suspension.

These are just a few I found with a quick search. Your front axle sees more leverage during braking and turning situations than the rear, so the front springs are more susceptible to damage by wrap or twist and the likelihood of breaking or spitting the blocks out causing you to lose control is greater, not to mention the effect on your steering geometry.
There are three proper ways of doing it, add a leafs, new leaf springs, or hangers and shackles. Add a leafs are the cheapest, but will make the ride noticeably stiffer, leaf springs are more expensive, but the change in ride can vary wildly from stiffer to softer than your stock springs depending on what code springs you had stock, and which company you go with for new springs, hangers and shackles are also expensive, right around or maybe a bit more than new leaf springs, and take more work to install, but they will keep the ride the closest to factory.
