    Hey Webb,

    Good to see things moving along. I was looking forward to seeing some pics in the links, but the ones you posted give an AOL login error.

    Chevrolet offered them as an upgrade to its hairiest version of the 396: the 375hp L78. Selecting the alloy heads changed the engine code to L89, but didn't up the horsepower rating--that remained at 375. As this was a pricey upgrade, particularly for something that didn't provide any extra power, not many Chevys were built with the L89 option.

    When I bought my 1970 L78 in 1971, I used to get asked at the parts counter if I had the aluminum heads when I bought spark plugs, plugs were different for the different heads. :bowtie:

    Back in the 80's when I was going to car shows there was a guy that claimed he had a 1970 Camaro L89...but I haven't been able to find him again to confirm it. :(

    the L89 option was canceled in October of 1969. so it is possible that one of them made it in to another model like a Nova or Chevelle. however the 1970 Camaro did not go into production until January 1970. way after the L89 was canceled. so there were no L89 Camaro in 1970.

    A few years ago I saw a black 1970 nova with a L89 in a magazine. it had a Protect-o-Plate and was restored by reputable company. it sold at mecum Indy back in 2013. but the code on the block was CKT. not CKO. I suspect if it is a CKO motor with aluminum heads, then they are service replacement heads. they were available over the counter for a long time. from what I hear the factory L89/ZL1/LS6 head had a tendency to drop valve seats.
