No need to bend the tube, just turn it around till you reach a suitable location where you can then extract the dipstick. Is more difficult if you have the twin carby linkages with the wheels at either end (yuk), but it can be done. I have also seen a tag welded onto the top of the tube to locate it to the manifold bolt too.
If it is hitting something in the sump, it should be the horizontal baffle (providing you have the Aussies Escort 2Lt steel sump and not the Cortina one). If you bend the dipstick a little to try to ensure it goes through the baffle hole cleanly, there should be no issues.
In one of my engines (I have 3 with twins) the dipstik sometimes hits the baffle, but with a wiggle it makes it in... This car has been driven hard in Autocrosses for 7 or 8 years and never had an issue with the dipstick other than the tube having to be resealed in to the block (use a good silastic cement)...
It aint rocket science.... Youv'e already done the hardest parts...
