So I went to do the compression test and everything looks good across all clys right about 155 but I did find two burnt spark plugs wires from the headers got a new sets with header covers for those two cly it runs so much better matter of fact I do not think it has run this good in a while but I do still keep on getting a code of lean bank 2 any help with this would be great oh yeah by the way it still ideals a little rough but not as bad as it was at all

Now look for vacuum leaks and make sure your connections down stream of the MAF are tight and not leaking. I'd use the propane method for vac leaks. Looking at the color of used plugs can give an indication of rich/lean running. Since you put headers on, if they are sucking any air into the exhaust upstream of the O2 sensor then it will trip the sensor into thinking you're running lean. I'd also check your header connections.
