Browsing Center Ville Auto's sight and came across this.. Would be cool if its really the covers for the export kit.
The layout of that website is horrible.... Anyway, it's a link to an Instagram post nailhead_matt factory experimental valve covers i forgot we stumbled across a decade ago. have never seen another set. my guess is they originally intended for export rockers, which ended up not being required for adjustable rockers which was an early engine export package, consisting of true 10 to 1 pistons, HP intake gaskets, and solid lifter cam with adjustable rockers. #nailhead #buicknailhead #buick #nailheadbuick He's a member here: @nailhead matt
That's wild! I know Tom T had quite a task when he designed his roller rockers to fit under the stock valve covers. Matt is a member here, but I don't think he likes us! Too bad, he has a lot to offer, guess he prefers the Facebook groups. I learned a lot from his Dad Russ when the Yahoo Nailhead group was still active.
I didn't think that it was possible to make a Nailhead ugly, but those valve covers managed it. I suppose it would be a great conversation starter, but unless there's something under them that makes them necessary, they would be conversation starters hanging on a wall.
