Oh yeah you can see those big square aluminum hold downs in the first pic, the shafts don't stick out farther than they do. And the by the looks of the crossover cutout they definitely look like iron heads.
But! If the rail doesn't extend inside the plane of the cover's wall (been forever since I've had a set of those M/Ts in my hands) and the actual wall of the cover is hitting, well obviously we can't grind on that so if shaving the hold down, or using different ones, won't get it, then yes different covers are needed. Although I don't remember having fitment trouble with factory heads and those covers, but that was with stock hold downs.
I would definitely look at massaging/replacing the hold downs before shelling out for different covers.
FWIW none of the covers I have in my stash would fit the Trick Flow heads; the problem there is the cover rail hitting the rocker stands on the ends of the heads. Had to grind just a little off the rail there, and trim the gaskets.
Gotta love hotroddin'!
