i am building from ground up a new Ls6, and i put CNC high performance heads on it, and was trying to button up the valve covers, and found out between my new PRW roller rockers, there isnt enough space for the stock valve cover baffel for the pvc valve that goes thru the valve cover, is this baffel needed, or is there a fix and size change that i can find to make my stock valve covers work?

 

valve cover spacers might work. Check with the vendors..
