Will they work? Or is it even worth it?

I'm not a pro, and I don't have any access to a flow bench, but I've ported a few sets of heads, not all mopar, and they have always made big improvements on the engines! lol. My old 360 picked up almost half a sec in the quarter with just my porting and a windage tray (which I doubt helped much, it didn't spin past 5500). I just wonder if it would choke my engine? Thanks IQ52!
