Has anybody here ported a set of the Dart 180cc Iron Eagles? I'm in the process of that and I'm not sure what else to do. The intake ports have been port matched and the mismatch in the bowl areas have been cleaned up. The throat of the ports seem to go along with the 85% rule, and the short side seems to be pretty good. I still plan on cleaning up the casting flash and polishing the exhaust runners and combustion chamber, but I wasn't sure if anything else really needed done. Any suggestions? By the way, does anybody know the flow numbers for these? I've seen many different numbers and wasn't sure what they really were. Thanks for any help.

 

the exhaust numbers look pretty good compared to the previous dart/wp heads. I think they are in the mid 170 range. Intake flow seems a little low, nov 2000 chp has 210 at .4 and 209 from there on up.
