wtb intake manifold

im lookin to buy an intake manifold with nitrous bungs welded on. as i do not want to drill another intake since my other is on my wrecked car, Nor do i wish to use it at all. when i drilled and tapped this one they nitrous nozzels didnt stay in well so i would like something for them to grab to. if anyone knows of a good manifold with nos holes in it be great . Thanks.
