I'm looking for an emissions legal intake. Is the GMPP ZZ intake manifold 10185063 a good upgrade over the stock LG4 intake? I can get it for $155, which is how much an edelbrock egr maniifold is.

Here's what GM says:
"This manifold is used on all ZZ series 350 HO engines and also can be used on all small-block Chevrolet's thru 1986. This aluminum manifold produces the same horsepower as the previous high-rise design, but provides increased hood clearance and more versatility. It has a dual-pattern flange that can accommodate both standard-flange Holley and spread-bore Quadrajet four-barrel carburetors. This manifold has provisions for all late-model accessory brackets, EGR (exhaust gas recirculation), and an integral hot air choke. A heat shield can be mounted
underneath the manifold to prevent coking when EGR is used."

 

I'm not sure if it's better but I sold my intake off of the ZZ4 I bought for like $50 used on this board. I went with TPI on the ZZ4. Keep an eye on the boards for a used intake, they pop up quite frequently.
