"EQ" Magnum cylinder head differences

The quickest way to tell them apart is the China brand has a Freeze plug in the end just like the factory.

True NZ EQ's do not!

EQ-CH318A is for the LA intakes and the EQ-CH318B is for the Magnum intake.

You beat me to the punch. I actually went out to the shop to look at a NZ EQ to make certain before I posted as my mind aint what it used to be.
