Bigger injectors/new chip?

Ok I had another thread running on another problem and I've narrowed it down to timing and fuel. So I have another set of wires on the way and I was wondering If I should be using larger injectors. I just installed my 355 has trickflow 195cc 72cc heads, XFI268HR13 cam, forged bottom end, 1.6rr. The injectors I'm using are the bosch 22lb. Do I need bigger injectors for this setup? After seeing the headers glow and the dry black plugs I'm wondering if it's getting enough fuel. Also should I have a chip programmed for this setup? And if I do were can I get one done? I'm sure this thing will fire right up once I get my timing and fuel mixture right. Just need a nudge in the right direction. Appreciate the help.
