The 289 will be fine for a 331 ci stroker, and most likely a 347. I bought a block from a guy who was putting a Mickey Thompson forged crank into a 289 to make a 360. That was about 15 years ago and before any "kits" were available.
How many of these posters has actually measured various 289's and 302's cyl depths? A poster on FordMuscle.com claimed to have measured at least 5 of each and determined that the 302's average no more than 1/16th of an inch deeper.
Do a search online for 289 stroker and you'll eventually find a guy who had a 347 ci 289 that he raced over and over with no ill effects.
I have a std bore 289 hipo cast in 64 that will be built into a stroker.
