ZL-1/L-88 Aluminum Heads 3946074 Feb 69 Dated NICE
This is a pair of factory Big Block Chevy aluminum heads. The part number is 3946074. These were used by GM on 69 Zl-1 and L-88 engines as well as the 71 LS6 Corvette. These heads have very hard to find Feb. 69 casting dates!
These heads are in great shape and were recently taken off of a running engine. They have no porting on the intake or exhaust and the chambers are not deburred or modified. One rocker stud boss has been nicely repaired and used for over a decade with no issues. These heads were removed from a 68 Yenko Camaro to return it to its original configuration.
