How did those blocks work out for you?

 

I don't want to sound like an idiot, but i am just trying to educate myself. I have a 97 4x4, so its got the 3 inch factory blocks. Now i want to get a few more inches out of my truck so it sits like 5 inches high, so if i buy 2 inch blocks and weld them to the factory blocks that should work? And what about the front, coil spacers? And if i do lift it those 2 inches, do i have to worry about modifying anything else? Shocks, steering components? Any advice would be greatly appreciated
