Stroker 340>416 Build Advice

Hey all!
Building a stroker 340/416 for my 70 Duster 4spd. Already bought the rotating assembly, getting the SCAT 416 all forged with the dished -20.5 cc pistons. Trying to figure out heads/cam and looking for what others have done or had experience with. The car will be a street car running pump gas so I was looking at about 10:1 CR and sticking to AL heads which I believe would be about a 65 cc chamber. Any suggestions on what heads and cam to use?

Look for a head with intake ports in the 180's cc and mid 260's to 270's cfm by .500
Cam in the 250 @.050 108 lsa with a few degrees ground into the int for a little kick. 280's -290 dur.
Dual or single, dual will be better off idle the single up top..though the dual plane can hang into 6000 rpm too. Oh and check out B3Racing for a geometry kit before ordering pushrods. More power 'imo less spring required to control the valve too'.
