And boy, I know about those f*cking manifold bolts. I snapped off just about eryone of em. Machine shop went easy on me and only charged 100$ to have em drilled out and tapped. About 10 or so were broken and all but three flush. 400$ total for a 3 angle valve job including that 100$. Good thing is this already had (and yours does too, mine was a '76 as well from a lesabre turned stock car) and it doesn't need hardened seats if the originals are fine. Good luck! Oh, and if you decide to repaint it GM blue, let me know what brand you choose. I am on the fence because I am super picky about the shade. I want it to basically look 100% like the faded blue on your valve covers if a shade lighter because it's new.
