Are any year OEM vortec manifolds that black plastic like Ford v6 stuff?

I recall seeing them on truck motors but maybe they were all black coated aluminum?

The plastic ones cant be torqued and bent, if you've got a leak you just pull it and retorque it, it remembers being straight.

Just got ARP 12pt chromo bolts but plastic would be an upgrade IMHO. I know they hold boost Ford proved that...
