That 242-248 is going to be the ticket for that combo will make the power where you need it and if your lookng at a 6,500 red line this cam will have more usable power than the other bigger cams.
Personally that combo would love the cam im running in mine its a solid roller 243-249 @.050 with 585" lunati VooDoo solid roller its all the cam you'll need trust me heres quick vid of my engine getting timed. this thing revs real quick and is making great power.
And yep if your looking at heads check out pro-filers 210's the new big dog in the head market but if your a dart man you will not go wrong with the 215's pro 1 killer head aswel.
Heres a pic of my 210 pro-filers
