curious to know what these heads flow throughout the lift intervals. I'm not having much luck finding that info on them.

It appears they show up in this database of head flow numbers, although the entry title does say 'ported' so who knows?

Search for "DART PRO2 Ported SF600 Alum".

Go to Dart website. Click on resources. Select tech library. This should bring up all the options of heads available and you can select the tech notes. I did not see a full on flow chart but did see general flow numbers listed

I don't remember where I got those number from. There was a time many years ago where someone who worked for Dart would send me flow numbers. While this link doesn't have any other numbers for that head, that link / list is over 7 years old and has over 600 less listing than this link. http://www.magneticlynx.com/carfor/tablehdc.php

Not to derail, just a note - I saw yesterday, the foundry that casts steel heads for Dart has filed for Chapter 11 Bankruptcy. Nothing on the Dart website, and I would imagine they have a contingency plan in place. Hopefully the molds and tooling won't be locked up in lengthy court proceedings.
