Hi guys. I have a head that i had in storage and i'm not actually sure what it is.

It does not have H89, H72 or H75 on it.

And it has smaller ports.

Although it has an open chamber, like the h72 & h75, although the H89 has a kidney shaped chamber.

And an a12 GX has a kidney shaped chamber also.

Could it be, that this head is a a14 GX head if there is such a thing?

Its in original condition, I have valves and springs in a box on their own also.

H72

But it doesn't have h72 on it like my other h72's?

I know. Ive gotten several heads without casting marks either, its an h72 tho. If you have others compare it, im sure you will see they are the same. Altho there is one h72 that is different slightly, the 104? casting I believe.
The one you pictured looks exactly like my 106 casting.
And its also drilled and tapped for both a series intake flange patterns.
Its an h72, for sure.

They are usualy single valve springs. But I have seen one with dual in a yard.

Thats the thing... i do have a lot of heads, and it seems to be like no others, the only one it compares to is the GX. As in port size, and the no casting number. It has the big combustion chamber, thats what made me think its either a h75, h72 or a14GX if there was such a thing.

I dont have the orginal valve springs... although i have the orginial valves. So i dont know if they came with double or single...

Thanks for your info red banner.

thats your h72?

Looks like an H62 head from A13 engine:
* dry manifold
* new bolt pattern
* open chamber
* small oval port

Measure the height of the intake ports. Are they 30mm or 32mm?

DD, they are 32mm.
