You're getting old mate to skim them though, right? That gasket face looks like the surface of the moon

I think you're right there Action Man, but I think that first "letter" is just an upside-down 1. They don't use "I" in their codes to avoid this confusion.

I reckon it was stamped wrongly ie: backwards, meaning it should read "1J14"

1 = 81
J = October
14 = 14th day

That's the only way I can see it lining up with the usual layout.

Interesting...........  like to see the test bench flow results.
They apparently have half the size of that exhaust heater thing and the short turn radius is opend up or something he was telling me i had a look at these heads and they are a tiny bit different to the xb ones i did last week

I would be interested in seeing down the throat of one as I clearly remember how bad my blue 2Vs were before I gave them some love

Yeah me too. I have a feeling that early Aussie 2Vs were shockers, for the size of the ports they don't deliver ... They're only marginally better than a 351 Wheezor. I remember reading something like 180cfm on them whereas US 2Vs go up around 200. That's around 40hp difference when calculated out.

I think it's just in the way the throat is cut in them, and the short turn is horrible. Also the casting roughness and daggy parting lines were shitty down the port.

Yeah I remember the exhaust crossover port being huge. It's about the size of a Windsor exhaust port. Not needed in Aussie climate.

I have blue & black closed chamber heads, some time might see if neighbor still has his flow bench & compare, but I'd say wound be minimal flow stock.

Sean/Clevo120Y flowed a 2V closed chamber few years back

7.3 Zilla.. yes please. If they're around the same price as a coyote, I know which one I'd choose.

yup crunchie valve stem seal bits,these heads have never been touched and so far look vg,action man went into full boost mode and stripped both heads already and soon go to the machine shop to tank them up,and take it from there i think these late black heads will be a good starting point for my 400 build .
