Best Roller Cam For a 351w? NEED HELP!!

[BowTie Eater 5 Liter]

351w Short block
stock 5.0 fuel lines
trick flow twisted wedge heads
trick flow "351" intake
24lb injectors
pro-m 77mm mass air
trick flow 1.6 Rocker arms
crane hi-6 ignition & ps-91 coil
190lph pump & AFPR
Stock 5.0 t-5 (when she blows, probably a Termec TKO)
bbk 70mm t-body & egr
3.55 or 3.73 gears
drop engine mounts
new flywheel
new distributor
new (or used) oil pan

NOW FOR A CAM, IT WILL BE A ROLLER CAM, HOW MUCH LIFT COULD I HAVE WITHOUT PISTON-TO-VALVE PROBLEM?
I want to stick to the trick flow name if possible & was wondering if I should use

stage 1(Duration@.050 221*/225*, lift.499/.510, Lobe seperation 112*)

Stage 2(duration 224*/232*, lift.542/.563, lobe sep 112*)

or stage 3( duration236*/248*, lift .574/.595, lobe 110*) cam?
I dont want to cut the pistons, but might get 10-12:1 compression pistons(dont know what the stock 351has?) also for pushrods I have no clue.
I will use the stock 351 until funds grow, with the exception of fuel injection, but with the stock 5.0 19lb injs
If you can suggest any other things missed.

thanks!
