I have a question about "Cylinder head GT 190 machined for road use"

Hi, do you have a volume of this head for calculating the trapped compression? So only the head without the radius of the piston and any squish. As far as I can see the head has no machined squish?

Regards,
Bernhard

Accepted Answer

We do not measure cylinder head volumes in this way, for a true compression test you need to assemble your engine and find the volume at TDC.
