head swap?

[driftinggrifter2]

Hi guys,
I was wondering if I could swap out my 94 3.4 iron heads with say aluminum heads would it mess up my comp ratio or anything that yall could think of? Probably a stupid question since not many of ya'll have v6 but worth asking anyways.

Compression will stay the same if the combustion chamber size stays the same.
The smaller the chamber, the higher the compression.
The larger the chamber, the lower the compression.
