Default Re: ZL1/L88 198 intake, NOS 074 heads

Kurt,

The last year these heads were cast was 1976. I've had several sets and have done quite a bit of research on the 3946074 heads, especially since I own the cars these came on from the factory. There are also particular stampings that separate the assembly production heads from the over the counter heads. I was hoping your dates were for late 1970. Thanks, Warren
