NOS GM Big Block Chevy 14011077 Aluminum Heads Rectanguar Port Open Chamber
 

This is a pair of original New Old Stock GM cylinder heads for a Big Block Chevy Engine. These heads are brand new in the original GM boxes and have never been used or installed. The part number for each head is 14011076. The casting number on each head is 14011077. One of the boxes has a partial part number tag. The other box has the cast iron 990 head part number on it so there was either a tag over that part number or the boxes got swapped at some point(These came to me with a number or NOS heads. These heads are the ALUMINUM high performance versions with rectangular intake ports and open style combustion chambers. The 14011077 head was an upgraded version of the 3946074 L88/ZL1 head. It was used on the infamous LS-7 454 crate engines and was also a very popular performance head in both automotive and marine applications. What a rare find!

These heads are in amazing unused condition as shown. Both heads are still in the original GM boxes and have never been used or installed. These are just as they left the factory. The castings look great with some factory casting deburring in one chamber and one Winter's Snowflake on an outer exhaust port is weakly cast. These are simply amazing never assembled heads. They simply do not get nicer than this!
