pro action "iron lightning" but i think they require special pistons (to clear spark plug), and possibly different rockers and rev kit but i'm not sure.

go with the darts. The pro's do have better flow numbers, but if you are running a dome piston you will have to grind on it to clear the head. Also with the pro's, they have been known to crack the valve seats.

HUH?? Ive run my 64cc PROs on two different motors, both with domes and I just bolted them on and went. I love them.

You might want to hold off on which head to use . I received my Dart dealer update today , and they are now coming out with the 200,215,and 230cc heads in their new Platinum Series Iron Eagles. According to the spec sheet , this series head in the 215cc variety will now flow right at 300 cfm @ .600" lift out of the box , far above the standard 215cc Iron Eagle and Pro Lightning 220cc head . The Platinum series heads are also supposed to have redesigned combustion chambers, profiled valve guide bosses , and better casting characteristics. I'll be happy to post more info after the PRI show .

They are not priced yet, and they do not have a part number yet. Should be available in early 2004 .

Yeah, sorry I actually forgot about this post. The latest news is ........... still waiting. Dart made their first run already, but decided to make a few adjustments. So we might be set back another month or two.
