What's the specific question?
oldeskewltoy has had A LOT of threads about heads & checking volume on this site, and at least 1 gotta be about that head and if he hasn't answered it, it's not a good question.

A standard big port 4AGE head will have a typical volume around 36 to 36.3cc’s and a chamber volume with a standard head gasket of 39cc. Note an un-cut head is 116mm (4.566”) thick. Taking a .004” thick cut on the 4AGE head will reduce the volume by about .5cc’s. If you use a thinner then stock head gasket or mill the head more the .005” you should consider getting adjustable cam gears to correct cam timing.
