sbc heads
 

hey guys if you have 64 cc heads and you deck the heads .020 what will that make the heads now thanks.

Impossible to caculate due to the combustion configuration, but there is a calc. to see how much compression would change.
Example; if you had 12.5 CR and wanted to get 13.5 CR with a 3.75 crank, it would take .022 removed from the head.
Calc. listed below.

Zip.
