Hi all, does anyone know what the original stock height of an H72 head would be ? I'd like to check & see what its at now to figure out how much has been milled off before. Its stamped H72, I think its off an A14 from a B210.

Who's got these facts floating around out there????

Thanks, Evan

come on guys, anybody know this stuff? Dodgeman, DD, all you Datto guru's. I've searched the wiki but no luck on oem head thickness.

Thanks, evan

Thickness? Measure the CC to see if it has been milled, but dunno what an H72 head should be.

I would eyeball the thickness of the head face. How does it look compared to other heads you have?

from memory they are 74mm
i will check my listings at work tomorrow

Having never done that before I guess I didn't think of the CC test. I just assumed one could start with an OEM height/thickness & deduct the current # to tell what'd been removed.

If you do have that # Dazza I'd appreciate it!

Thanks ,Evan

BTW DD - you get what you need on Sat. from pull a part?

I have a gx head that's 73.6mm.
I don't know if it's been shaved, though. If it has, it's not much. The area under the thermostat hasn't been touched.

Interesting how that's not in the service manual. I was expecting to find something like a "service limit" for head thickness. You know, like for rotors.

that was kinda my thought as well, rotor's a good example. I've got 2 or 3 other heads but their round port not oval, dont know if it matters but their different so a comparison's kind of tough.
