But in this case just the headers did add power?

Very nice. So it’s safe to assume my ported blower, 108mm throttle body and headers added power

The ported blower will definitely add power.

Maybe I read it wrong but thought this is the tired shortblock dyno before switching to new engine?

That is absolutely correct. That tired factory engine definitely impressed us. Your point is a good one since it would be safe to assume a "fresh" stock engine with the same modifications would produce more power but we cannot prove that.
