Is this a good gasket set for my Lower intake? Or should I go with OEM?

I also got these for another option. Valve Cover Grommets - Quantity 12 - http://www.gmpartscenter.net/oe-gm/25534749

Valve Cover Gaskets - Quantity 2 - http://www.gmpartscenter.net/oe-gm/24503937

Supercharger Plenum Gasket - Quantity 1 - http://www.gmpartscenter.net/oe-gm/24503911

Throttle Body Gasket - Quantity 1 - http://www.gmpartscenter.net/oe-gm/24503648

Fuel Injector O-Ring Kit - Quantity 1 - http://www.amazon.com/gp/aw/d/B000C9...=ATVPDKIKX0DER

Lower Intake Manifold Gasket Set - http://www.amazon.com/gp/aw/d/B0049Z...A2EXL7LTROORSB

All of the above comes out to $145.

Now should I get this http://www.amazon.com/gp/aw/d/B002LW...=SS115&simLd=1 and the other parts that I need that don't come with this set I will just order from the above options. Is this Fel-Pro set any good or should I just stick with the above options? Also this set is will make the overall price lower, but my main concern is, if this set is any good.

Please let me know your thoughts on this!
