Ah, don't let the bent forks get you down!
Assuming a fork is bent by a head on crash, the result is to reduce fork offset ("rake") and so increase trail. The same crash is likely to bend the frame, increasing the head tube angle.
All these things can be measured. If you have a frame you like, disregard the likelihood that it may be bent, and measure it as is.
But that's a hypothetical. I'd recommend trying a few frames that are guaranteed NOT bent, see how you like them.
