I am looking into the Dart heads, they are the cast iron ones check out this auction for the detail if you would. I would like anyone input on them.

I am also looking into the same style set but with 64cc chambers and the stait plug.

Any thoughts anyone?

I use that exact head...Dart Iron Eagle 180's with 72cc chambers and straight plugs. They are far superior to most GM heads, Vortechs being the exception. My car runs pretty good.

I'm happy with mine. They run good out of the box and have a lot of potential with a little extra work.

Darts are very good heads for the price. You can also get more info at www.dartheads.com (http://www.dartheads.com) Just my $.02.
