| Description | Original GM 427 ZL-1 Cylinder head bolts. These are the real deal. The 427 ZL-1 Head bolts are longer and have more threading than the standard GM head bolts. This is due to the aluminum block and to give the bolts more holding power and strength when installed. I have included photos to compare the standard big block head bolts and the longer ZL-1 bolts to show you the difference. This is only the 2nd set I have owned in 30 years. Included in this listing is used GM# 3952330 long bolt (24) measuring 7/16-14 x 4-9/16 and used GM# 3952331 short bolt (8) and measuring 7/16-14 x 2-1/2. They can be found in the GM part book under 0.293. NOTE: the squiggly head marking. These were originally manufactured by Maynard Manufacturing in Warren Michigan for General Motors. Applications: 1969 Camaro 427 ZL-1, 1969 Corvette 427 ZL-1. |
