Best performing non offset Small block Mopar heads

Are they any good?? I remember seeing pics of a set recently but I’ve never heard much about them. They take Chevy style rockers?

got a good friend running a well done set on a 70 Duster drag car. 260 something solid roller, 904, 3000 pounds, maybe a touch more, 12+ to 1 compression. Well sorted combo.
Been 10.27 best at 128.xx with them.
My brother has a set too, had some issues getting them installed in his 66 Dart. The exhaust ports are raised over stock, and the head is physically bigger. Headers car be a real pain in the ***, even worse obviously in an early A.
They make power, but nothing that i would say that separates it from others for the xtra trouble. Wouldn't be my first choice just because of the messing around needed from the several differences.
My brother got his nicely ported set along with older set of rockers and an intake for 1200 bucks at Norwalk 3 years ago in the swap meet…on my advice he bought them. There are also different revisions of them too. More than meets the eye with these, believe me
Now wish i hadn't offered the advice, and he had stayed with what he had
