9206xxxx numbers date back to VC/VH commodore.
Cant find 92060988 in any commodore parts books.
Closest match is 92060975 which is #3 HEI spark lead from a VC-VK V8.
Cheers,
Mick

So the 92060988 is a little blurry, but the 92060990 is really clear.
Actually, it could be 92050990???
Does that make more sence?

Looked a bit harder at the later stuff, realising theyd be EFI headers from the spacing shown in the pics.
Part numbers 92060987 & 92060989 (obviously the machined variant of those raw cast numbers) are the VP-VS cast-iron headers that replaced the early EFI tubular style.

Mick

That narrows it down to 2 models.
The guy I bought it off said VP top end.
So hes probably right.
Will try and get some more about the computer now and see what that tells us.

PS Mick
Should there be a bung in the headers for the oxygen sensor, or would it go in the exhaust after the headers?
Also, what did HSV use these headers?
Is there some parts diagram of the stock VP/VS V8 exhaust that I could check out for diamaters, CATS, mufflers, sensor locations etc?
Cheers again

The oxy sensors are in the headers, about 3 inches up from the first joint. If you cant find them, Ill post pics of the tubular style (thats all I have in my spares).
There are no other sensors on them except those oxy sensors.
HSV systems used tubular headers, not cast like these.
Most of the systems were simply pipes off the headers, joining before the cat (RH side had a cross-pipe in front of the gearbox) then from the cat a single pipe to a muffler before the diff, then a sigle pipe to a resonator behind the diff.
Basic VP-VS HSV systems used the same single cat arrangement up front (but with tubular headers), and it then split off into 2 mufflers before the IRS, then a 2-in, 1 out resonator on the rear.
Full HSV dual cat systems ran 2 cats, 2 mufflers, and a 2-in, 1 out resonator on the rear. They didnt have any crossover pipes, so neither side met until the rear res.
The VS HSV system is a wierd size that I couldnt adapt to (I only wanted to change the rear res at first).
It worked out to be someting like 2 x 2 1/8" pipes.
Instead of stuffing around, it was easier to do a dual 2.5" cat-back arrangement.
Also, the HSV systems Im describing are for IRS cars - live axles are different again.
As this isnt in a commodore, what the factory did doesnt matter too much, as your car will be very different under the floor, but Id look at going dual cats if you have the space, and dual 2.5" all the way back.
Dual cats & twin 2.5" gives a great sound, nice & deep & rumbly when cruising, and a real roar when you give it some throttle. Only prob I have with mine is a bit of resonance around 95-100km/h in overdrive, but drop it back to 3rd & its fine.
Cheers,
Mick

Also, just to add, a pair of stock EFI 304 or V6 cats (they are the same as each other) will flow more than enough when you mount 1 on each bank, and this will help keep the budget in check.

Mick

Great advice Mick - thanks.
Im really keen to keep it as quiet as possible.
The car came with 2 cats, which I assume will be fine - not sure what their diameter is - cars not with me at the moment.
Exhaust guy I spoke to was panicking about fitting cats to an HG saying theres no room and itll affect ground clearance.
He seems to think there only room for 1 muffler , behind the diff running sideways, like the stock HG V8s.
Anyway, Ill talk to him again and give him your info.
If you were after quiet (ie take the kids to cricket and a sunday picnic) with a subtle V8 burble, would your recomendation change?
Also, its a Supra 5 speed box.....
Cant wait to get it on the road and registerred....
Thanks again

If you want a quiet system with a nice burble, the stock VS clubby mufflers & res are the go.
The resonator is quite small - a round barrel with HSV embossed in the top above the exit pipe.
HSV enhanced rear resis are more box-shaped, same embossing, but quieter.
Im not sure if you have enough room for a seperate resonator & muffler like a commodore runs, but a good exhaust place should be able to sort out what will work for your desired level of rumble.
Cheers,
Mick
