a little valve cover paint!

[Dmnys]

well decided to change my valve cover gaskets since there was a major oil leak and while at it decided to give the valve covers a little "life" changed out the valve cover gaskets and took care part of the leak learned that i need to change the intake manifold gasket as well cus im getting some leaking from there as well! so know should i get a performer intake or wat do u guys recomend and will there be any difference? im sure there has been threads of gauges but i saw the ones on the picture below and love them original with a twist on new! can anyone tell me if is just LED lightbulbs or theres more to it? here are a few pics of the process of the valve covers paint and the gauges!
