I checked one of the combustion chambers tonight.
A 1/8 piece of clear acrylic plastic with a hole drilled in it. Used some Vaseline smeared around the bore . Pressed the clear piece over top and started adding ISO with some green food coloring . I simply used a 10ml syringe and started counting.
It is a bit of a tedious process , you have to be patient putting in the fluid, and when u get close to full need to get that air bubble below the hole to fill .
I had some spillage on filling and ended with 91cc . I know that was to high and a result of my sloppiness! With the chamber completely filled I didn't reverse and measured as I took it out. I got 85.5cc , allowing for the smallest amount left in the chamber and a bit residual on the plastic, I will call it 86cc.
To the best of my knowledge the heads have been cleaned up twice. Given a 88-89cc oem head I feel the 86 to be in the ball park?
