Join your small-block heads to a Stahl-pattern header
Kooks 7032-KIT adapts stock inline six-bolt small-block Chevrolet heads to a Stahl seven-bolt header pattern. The mild-steel plates include gaskets and bolts for both interfaces, giving your installer the parts for the pattern conversion.
SKU: 7032-KIT
Made for the stated 23-degree head pattern
The plates are 5/16-inch thick, with countersunk holes to mount to the stock head and threaded holes for the Stahl-pattern header. Match the head port and both bolt patterns to the actual parts.
Account for the added thickness
The plates sit between the head and header. Have your installer allow for that 5/16-inch thickness when checking the header’s position and chassis clearance.
Ordering and delivery
Estimated lead time is 4-6 weeks. Delivery may be faster depending on stock levels. Shipping is charged separately.
