I found a good deal on a set of Dart Iron Eagles. 180cc runners/64cc chambers. Will these heads choke the engine? I will have a heavily ported SLP runner TPI setup.

They are a really good quality cylinder head. I have seen a few sets...very nice. They don't flow unbelieveably well out of the box, but decently so. I wanna say around 225 cfm at .400 lift (but don't quote me, or hold me to it) The big difference is in the way they respond to porting. I have seen some flow numbers on a heavilty worked set of 180's and it was quite impressive. I doubt they would be much of a restriction for you with your current setup.

There are flow numbers for the Iron Eagles at the bottom of this page.
