Default Injector Recommendations

I purchased a pretty built up car last year. It's a 6lr block with heads, cam, fast intake, long tube headers, and YT roller rockers.

The previous owner claimed it made 460hp to the wheels, and gave me a dyno sheet to back it up. Thing is, it came to my attention the other day that it's still got the stock 28.8lb injectors in it. I've read these are only good for around 430hp. So either he BSed me, or these things are being pushed to the bleeding edge of their duty cycle. It's got an upgraded fuel pump, but I don't think that matters unless it increases the fuel pressure.

Anyway, what would you recommend? I don't need to to be much faster. Maybe someday over the rainbow I'll SC it and do E85, but probably not. What would be the best injector/flow rate to handle at least e85 at a reasonable price?

Do you have any way to verify the dyno pull?

Well, I could pay a few hundred to run it on the dyno, but if I'm going to do that, I'd rather just do it while it's getting a tune.
