349cui build up

Hi together,

I am building a new engine for my 1970 dart.
Now some questions comming in my mind. What will be the best head and cam Combo for my application.
Here are the facts:
- like to get 13.5sec in the quarter
- car is street driven and will see the strip 4-5 times the year

- 3.55:1 rear gear
- 727 with shift kit and 2500stall mopar converter
- 318 .06" over
- cast piston 8.4:1 truck sluts (have to cut valve reliefs)
- 3.51" stroke mopar performance forged crank
- windage tray
- performer rpm intake with 1/2" plenum devider Cut down / alernative a China crosswind airgap

I currently have the following parts laying around:
- portet 340 x heads with 2.02" / 1.60"
- ede heads from hughes with 2.02" / 1.60"
- comp XE274H ( http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=628&sb=2 )
- crower 31320 ( http://www.crower.com/camshafts/mopar-273-360-la-pro-street-solid-cam-278-fdp.html )
- stock sheet rockers, 1.5 and 1.6 roller rockers

What do you think about the best combo?

Thanks for help
