I have searched but I can't seem to find the results for what kind of flow numbers a set of stock 3.2 heads can provide. Does any one have this information?

You can probably get a local perf. engine builder to put it on a flow bench for a buck or 2. Trying to feed an engine simulation program?

You guessed right wdonovan. I have 3.2 heads on my car now (all stock 1985 M491 Carrera) however I am building a new turbo motor as well. I have a set of 3.2 heads in route that have some mild port clean-up work and I will probably take them to a local engine builder and have them flowed. I wanted the stock 3.2 data as well because I want to examine all the possible configurations for this new engine.
