I have a pair of Dart Conquest heads,they have 220cc runners,2.08/1.625 valves. I am not sure ,but I think they were discontinued.Are these good heads performance wise?What could they flow with a port job?The bowls are already blended.Would I be better to save for some Air Flow Research heads?

It's exactly the same as the Pro-1. They just started life with a different name. They will flow well over 300 with a good full port.

I am just trying to get some ideas for this winter.Right now these heads are on a 355(I know they are to big)10.5to1compression,Crower solid flat tappet cam 244@ .050 intake 250@.050 exhaust,.545lift in..512 ex.105 lobe separation.On top is a 750 dp,Performer RPM .I've got 1 5/8 headers with Flow master scavenger collectors.Under the car is a 350 turbo with a 3000 stall,4.10 gears.The best I've run is 11.89 @ 112.9 1/4 /7.55@90.6 1/8,60 foot 1.64.I don't have very good air here in Bristol TN.I'm going to build a 406 this winter and try for high 10's. I drive to the track around 30 miles so I need to keep it street-able. Thanks for the replies.
