After a unexpected bout of bad luck lately (on multiple levels) I am now in need of a different cylinder head for the 69 Skylark. It started with a simple 2 to 4 intake swap went bad due to auto shop (had them do the work since I had to remodel due to flooding) that worked on it tried to float the titanic with silicone (had to use engine hoist to remove intake!) and silicone unknowingly down in the bolt holes. A intake bolt snapped while torquing 1/8 below the surface and ensuing attempts to tap out the broken bolt resulted in the head turning into a paper weight. This is the worst possible time for such a issue to arise and our Skylark sedan is our backup vehicle. It ran great and a 4 barrel qjet upgrade would give some much needed fuel mileage and performance boost over that 2 barrel. I would like to be able to source a usable stock spec one to avoid having to rebuild any heads and reuse the stock 69 rockers, etc. I have a core 72 350 thats been indoors for decades, but something tells me they changed from 69 stock specs. This being my first Buick 350 (used to nailheads and 455s) I am not as well versed in the small block tech.
