Re: LS7 Head Info Needed
The 1970 Chevelle LS-6 used iron heads. In 1971 the LS-6 was only available in the Corvette. It used aluminum heads.
I have learned that they took the ZL-1 open-chamber aluminum head and used it on the LS-6 short-block with close-chamber heads to lower compression. The very last Corvettes got the new iron open-chamber heads that were developed in 70-71.
