You can chose, Edelbrock, Dart, Brodix, etc. avoid China imports, you may be lured in by the initial cheap price until they drop a valve or seat on the second pass on your new motor.
Name brand.
Oval ports on street and mild motors.
Don't bother going over 6500 RPM, you don't need too!
You forgot to mention the Air Flow Research line of heads.
They are quite possibily the best "out of the box" aftermarket heads on the market today.
