ccs after 5/1000 milling?
What does milling heads 5/1000 do to the ccs of a head. Looking at some 243s that have this done and was wondering what this will raise my compression too?
Thanks!

Milling .005" off should reduce chamber size about 1cc.
If no portwork or material was removed from the chambers, it would make the volume of the 243 chamber approx 63.4cc.
Compression on a 346 with stock head gaskets would be about 10.7:1.
