Eddie Motorsports sd7 manifold

[showdog75]

I'm looking for feedback from anyone that's used the Eddie Motorsports sd7 manifold. I'm putting Vintage Air on my 63 chevy II wagon as well as doing a ls swap. I've got a Alan Grove low mount bracket that I'm mounting the sd7 in. The bracket was made for a sanden sd508 but the sd7 will mount up on the lower bracket no problem but I'm having to make a new upper. I bought the Eddie Motorsports manifold to 90° the fittings out and make hose hookup easier and I just wanted some feedback as to whether they hold up well or leak down. I had someone tell me there leak prone but don't like to base my opinions on one persons experience.
