What intake & carb specifically? Roller rockers no problem, what ratio? Be sure lift doesn't require more of the guide tops cut down.

Did you cc the heads and stuff and calculate an actual 9 to 1 compression? Also thats a carb big enough for a 440. I think a 600 would better suit it. Also do you know what the converter stall is?
 
The reason you’re having a hard time finding a cam on the shelf is that flat tappet cam cores for SB Mopars are currently in short supply.

I don't know what negative experience(s) you've personally had with COMP, but i've never had an issue with their stuff. I'm making over 600hp with a comp cam and the cam was hand picked by one of the most reputable engine builders in the country, who just so happens to be a member here. Sorry if you had a bad experience, but it never ceases to amaze me how guys slam COMP so frequently on here and when asked why, they say things like, well my buddy..or COMP uses chevy lifters, etc.

I get it, that's rough to deal with. I've wiped two MPP cams. I'll only run rollers from here on out.
 
Isky 280HL. Hyd flat tappet. It is on 108 LSA, which will liven it up. Have your factory lifters re-faced.
