brodix and trickflow have in my opinion,the best looking machine work
dart, profiler ,edelbrock and AFR all come in a close second
some of the other stuff looks like its slapped together by drunk monkeys
Id suggest sticking to those 5 brands
which of the 5 I use depends on the application but BRODIX,AFR,TRICKFLOW. DART,EDELBROCK, in roughly that order for SBC, and TRICKFLOW,AFR,BRODIX,DART,EDELBROCK in roughly that order for BBC I feel are the best value,..I.E. price for what you get,
and obviously you need to research what cylinder head matches the engine build requirement you require
OPEN VS CLOSED CHAMBER
normal oval ports
MID SIZE OVAL PORT HEADS

BTW YOU CAN RUN A RECTANGLE PORT INTAKE ON OVAL PORT HEADS
theres a noticeable port mismatch but IT still works much better than most guys would suspect it might
those PEANUT PORT HEADS are just a bit worse than this, picture of the standard oval port heads with a rectangle gasket
EXHAUST PORTS
OPEN CHAMBER COMBUSTION CHAMBERS
DIFFERENCE IN APPEARANCE
RECTANGLE PORTS
