Could someone please let me know what the intake port length of an RB25DET head is? I need the measurements from the flange face to the back of the valve for each port.

Thx.

You need from the face of the head where it meets the lower intake manifold to the valve? I can get it some time for you tonight or tomorrow.

Yes, that's exactly the measurements I need. I'm assuming they're the same for each cylinder, but if you could check that as well, I'd appreciate it.

Thanks for the help!
