Original GM 3946074 Big Block Chevy Aluminum Cylinder Heads May 1969 L88 ZL1

[SuperNovaSS]

This is a pair of original GM 3946074 aluminum cylinder heads for Big Block Chevy engines. These heads have rectangular intake ports, round exhaust ports, and open combustion chambers.

The 3946074 heads were used on the following applications: 1969 ZL-1 427/430HP All Aluminum engine, 1969 2nd design L-88 427/430HP engine, and the 1971 Corvette LS6 454/425HP engine. These heads were also sold over the GM parts counter for years. It is not uncommon to see a set of these 3946074 heads for sale. However, it is uncommon to see a real deal 1969 dated set. These heads are just that. The casting dates are 5/12/69 and 5/15/69 as shown. This is a real deal paif of May 1969 heads that are like hen's teeth to find.

I have these heads listed up for auction on Ebay starting at $9.99 with NO RESERVE! That auction ends this Sunday(Easter) at 7PM Pacific Time. True 1969 dated 074 heads are very hard to find. Don't miss this set.
