single plug head has 58cc combustion chambers? right?

I measured 58cc of diesel fuel into a cleaned out head chamber from my 89 2.3... I just need to verify that this is the accepted head volume. anyone know?

been awhile, but pretty sure and a turbo head typical cc is 64.

thanks... does anyone know where I could find engine dimensional specs on the 2.3? I'm trying to figure out how much to mill off the head so I need data like rod length and such. I tried measuring my stuff but it's hard with the pistons still on the rods.
