I'm interested to know what the going price is for a A12 GX head?

I was able to find one that has been renewed (shaved, polished, reseated and maybe more).
It comes with a matched inlet manifold which i believe is off a later a14 oval port, as its made for a downdraft carby and is also equipped with water cooling.

Any ideas on what it might be worth would be much appreciated as i wanted to make an offer for it that seemed reasonable.

cheers in advance

probably depends on if it's a genuine jap spec gx head or a export a14 or a15 oval port

BUMP!
need some help here guys
i don't want to get ripped off so let me know what its worth

cheers

I sold my spare one to a guy for fifty bucks, I think I am an idiot I should have kept it
ade

well since no one else is helping out I'll say start at 60 bucks and work your way up to about 150. If that gets you a black eye I'm sorry

I think the guy wants more like 500+ !!!
He seems to think its worth the price of manufacturing an A12 into GX specs.

I'll find out at the end of the week how much he will let me have it for.

Does any1 have any pricing for porting an A12 to GX specs?

I went to a local head place and he wanted 300+ for a mild port and polish not including any valve work. He must have had his hand on it when i asked him.

How much is it going to cost to get a head up to spec?

You mentioned that everything has already been done.

For the porting alone you were quoted $300. Add valve seats, manifold port matching, valve guides, seals and a skim and you would be getting close to $500 and you still haven't purchased a core head!

The head is worth what the market will pay.

PS, $300 for head porting is not expensive. Depending how far you want to go, ie rewelding the chambers and starting fresh, you could quite easily double and triple that figure. If the air doesn't flow through the head then the rest is for show.

for that money, just go get an a14 head and pay $300 for it to be ported and cleaned up.... has bigger valves and will flow more than a gx head or gx spec head. then when you rebuild that motor get some hi compression pistoons as the a14 will drop the cr slightly, and you will have more than enough power for that 120y gino120y....
is this for that a12 you picked up?

Ok Gino 120y I have a a14 head you can have for 50$ has valve , springs but hasnt got the rocker gear on the top and no rocker cover sorry ,but i can get it transported to melb for nothing for you via my dads work you will have to picki it up ,Im sending some stuff to melbourne this week so let me know cheers geoff

I wanted to port the head off the engine i picked up, whilst keeping my original up and running. Replacing the worked head with the original and adding an exhaust system was as far as i wanted to get for the present time.
Wasn't planning on doing a full rebuild of the spare engine, but was dreaming about making a turbo setup for it. Was seriously thinking about dropping an A15 in but then it still wouldn't solve the problems that already exist.

There are lots of things i would like to do but it all comes down to money, time and effort.
