Nitemare Performance Fabricated Valve Covers are spectacular and fit all valve train configurations -- stock rockers, roller rockers, even stud girdles!

Each set includes:

• 2 breathers
• 1 two-stage PCV valve
• 3 thin-wall grommets
• extra-thick valve cover gaskets
• 8 stainless steel studs and 8 stainless steel, 12-point flange nuts

These covers feature a custom baffle welded inside the drivers side cover for the PCV valve. The PCV valve is also rebuildable and includes low- and high-pressure springs for custom tuning. Full tuning directions are included with the two-stage PCV valve.

The valve cover ends are canted on all four corners for extra firewall clearance. The covers are also asymmetrical — taller on the intake side than the exhaust side of the covers — providing extra clearance for the power brake booster and remote oil filter systems.

The base of the valve covers are resurfaced AFTER welding for a perfectly flat, leak-free fit.

And like your high-performance Pontiac, these covers are MADE IN THE USA!
