Pontiac Grand Prix Intake Manifold Gasket Estimate

I Was Told That My Intake Manifold Gaskets Were Blown. My First Question Is This The Same As Head Gaskets? And, Is It Worth The Trouble...

How Do I Fix The Low Intake Gasket. I Know The Part Is Cheap But The Labor Will Cost A Lot, So I Want To Fix It Myself. Please Explain To Me...
