"Please discard the order form for Super Duty Cylinder Heads included in bulletin 86-SM-6. The part number listed for the Super Duty 4-Cyl. Aluminum Cylinder Head is incorrect. Attached is a corrected copy of this form."
In keeping with our objectives of providing enthusiasts with the finest performance parts, Pontiac has made available new cylinder heads and 12 bolt flywheel to crankshaft attachment.
Attached are two order forms for super duty parts: one for cylinder heads and one for crankshafts.
As you review each order form you will find that two new aluminum super duty cylinder heads have been released to replace the discontinued 10038433 4 cylinder super duty cylinder head. Details of their features are summarized on the order form. In addition, official approval for respective race categories/class are also shown for each head.
Crankshafts are now available with 12 bolt flywheel attachment. Six bolt crankshafts in your inventory may be modified to the 12 bolt design by returning them to:
Norton Manufacturing Company 110 West Jones Fostoria, OH 44830
Special bolts have been provided. Details of availability for these special bolts and 12 bolt hole flywheels are shown on the order form for crankshafts.
All parts on both brochures are currently available except for the 10049875 Big Block S.D. V8 Cylinder Head (Small Port) which will be available on December 1, 1986.
