So there was a GS hood posted for sale here a couple of weeks ago. I spotted some MT4 bolt flange headers behind the hood being advertised. Gentlemen selling the hood was happy to also part with the headers as well as a 70 stage one engine block. From Florida, I was able to enlist the help of some family members in Michigan to pick up the booty.
Was this the hood? https://detroit.craigslist.org/wyn/pts/d/riverview-hood-70-buick-gs/7336730561.html
