Are 882 SBC heads good?
The 441 has a reputation as a good-flowing head among the production 76cc chamber heads. In this particular case, it lost out to the 882 head, but overall it's a decent head that responds well to pocket port work and larger 2.02/1.94 valves.

Are bigger cylinder heads better?

It's two half-ovals connected by a straight bar-most easily described as "two humps." Some of these are also nicknamed "Fuelie" heads because a version appeared on fuel-injected 327-powered Chevy Corvettes.

Are camel hump heads any good?
Any camel hump head is a candidate for a street engine build. But the key is what you have to spend to make them useable. A lot of them are cracked in the exhaust seat area. If you find a set of original stock heads, you'll need a valve job, exhaust seats, valve guides - maybe screw in studs/guide plates. via

Will LS heads fit a SBC?
Just to be clear: You can't bolt LS heads on a Chevy small-block. You can't even do it on one of World's regular Motown blocks. The key is the Motown II LS block with its redesigned water flow characteristics and head bolt pattern. via
