how much to cut head to reduce combustion cc's

[OUTLAW]

does anyone have the formula for cylinder head cc reduction



I had this infomation and lost it -but does anyone know what the ratio to head cut to cc reduction on a head

To clarify How many .001 milled off a head to reduce combustion chamber volume by 1 cc

 

[Sanguine]

340 and 360 - 0.0048" = 1cc
273 and 318 - 0.0053" = 1cc

 

[AdamR]

340 and 360 - 0.0048" = 1cc
273 and 318 - 0.0053" = 1cc

I think it depends on the size of the chamber to begin with.

your right Adam but I needed a approx to plug some figures into a formula


thanks Sanguine
