Friend of mine bought and uses a set on his nhra stocker 70 duster...they seem to be working ok...
I just got a set last week...bolted them on a engine...they fit...LOL....
my only dislike ...i am use the MP cast aluminum ones that have a lip all the way around the valve cover that holds the gasket ....these do not have one...I will probably put a small amount of rtv on the cover to glue the gasket to them...
but the rubber grommet i have fits perfect unlike the mopar cast ones..
Hmm I seen they don't have a lip and that scares me. Do they seem to have straight and level gasket surface. As long as they don't leak be a nice set
these are the ones i bought...

Only interference would be hanging up on a runner but they said there was no "M/T" lip so I don't see that happening...? Someone bring back the squarosh as cast model.
