Do you know how to identify if it is a Hartge head?

BTW, this head went to eBay.

That's odd it say's H23 right on it and H27's were not available till later after the H26.

I would assume Ryan will chime in on this.

That head is off a 83/84 H23. My head is stamped the same way (I own Ryans old car). In 84 they only made the H23 or H26 based on the 731 head.

[M-technik-3]

Why didn't your car come with the head?

[stumble_t]

So, I guess the next question is will an H23 head be a "bolt on" to a m20b25 block.

[M-technik-3]

No, it's more for an eta designed piston. 731 designed head is the 323i head which many plunk onto eta's when found.

Yeah, I asked, not worth it, or not possible .

Near as I can tell, this is basically just a head built especially for, or ideal for anyway, the normal eta block. Something equivocal to slaipping on an 885 head, but you maintain good compression. With a decent cam it'd be pretty sweet. Hell even without it I'd be willing to believe it'd get 190 hp/tq at the crank.

[Scott72]

Hartge used that head either in the H23, which was a Euro 323I bottom end with special forged piston to raise the compression to 10:1. They got 170 Bhp out of it. They also used that head in the H26 in 84 which was a 325E block and the 323I crank and rods plus custom pistons to make 190 Bhp out of around 2.5 liters. A nice lively engine. In 85 the H26 went to a straight 325I motor with the 885 head. My car still has the original 83 casting 731 head stamped by Hartge.

I was told it was an H27 head by my boss who i got it from... hopefully the bidder knows what he is getting because I am uninformed about this head....
