General Buick Tech / Re: Valve Springs replacement
« on: December 03 2021, 11:17:25 PM »https://www.vortexbuicks-etc.com/rocker_shaft_assembly.htmI did read this before I did the replacement, and it's funny when I first removed the old retainers in place , slide off the rockers in order, clean shaft and then placed the rockers back in the same order, and none of them have no Land R stamped on them. As you can see in the photo there is no L/R stamped on rockers.
Keep in mind this is an unopen engine; I know since I got it 32 years ago, and the first year a father gave his son my GN for graduated HS. 2nd year father took it away for missing College classes, kid protested and father fine now it's sold to me.
