LS1 LS6 Engine Valley Cover Built in PCV Valve w/Gasket For 2004 2005 2006 Pontiac GTO & 2004 2005 Cadillac CTS 5.7L & 2004 Corvette 5.7L 12577927

The valley plate is mad nice and when s test fit was performed it would not sit flush because of the plastic baffle hits the passenger side walls internal wall and also bottom outs I had to o modify the baffle to clear all the interior so it would seat properly after all that time it was installed and works perfectly
