The Edelbrock Signature Series Chrome Valve Cover is engineered for function and styled for good looks. These valve covers are triple chrome plated for long lasting looks and have stock-style breather baffles that prevent oil passage to the PCV (Positive Crankcase Ventilation) valve. The covers clear most aluminum rocker arms and moderate lift camshafts. It comes in a high-profile design and is 1-1/4 taller than stock. The low-profile design clears air conditioning and alternator brackets. The valve cover is made of steel and is not baffled. The breathers, gaskets and grommets are not included. It fits 5 and 10-hole heads.
