Re: WORH IT -- OR NOT ZL1 427 HEADS
Josh,
I would bet that back in the early 1970's these '074 heads
were considered the hot lick, especially if you ran headers.
I have seen 1969 dated '074 heads before, but that doesn't
mean they weren't over the counter parts. Just that they
were cast the same timeframe. I believe that the '074
heads were also an L-88 component, weren't they?
