Early HZ Inlet Manifold 4.2L

[Wombat7051]

Hi All
I am wondering if someone can help.
I was wondering which manifold is the correct one for a 12/77 HZ 4.2.
A or B??

As far as I am aware HX and early HZ use the left hand one (A). The right hand one (B) is a HQ,HJ, LH and pre ADR27A LX.

G'day Wombat.
I just checked out my 78 Hz that has the original engine and manifold on it, the one on the left A is correct.

Thanks Guys, I will experiment with cleaning methods on "B". I have read wash with High Pressure, then Mr Muscle oven Cleaner, then Acid mag wheel cleaner.
Any other thoughts???

Bead blast will make it look like new or try a can of carby cleaner. Make sure it's not corroded in the water ports before you do anything though.

I am about to send mine off to be hydro blasted, read an article about it and they do a lot of motor cycle parts etc , they were in Sydney but now I think Central coast and also spoke to some old guys at the Ballarat Swap Meet who do the same down in Victoria
