When looking for a good flathead for a passenger, what are some good tips to look for? Thanks in advance.

Always check the pan rails carefully down low where the oil pan bolts up. I've seen several that cracked down there between the pan bolt hole and the crack often continues up the inside of the block. You can't see the problem until the pan is removed. Usually at the machine shop long after the sale.
You wanting to build one or buy a takeout? Try to get a guarantee from the seller if you are buying a builder. You won't know what you have till it goes to the machine shop. Expect to pay more for a guarantee otherwise take your chances. They are all good just depends on what you want for power, cost, and appearance.
You will have no troubles finding an 8ba. Good parts availability and interchangability. 8ba's are not as prone to the deadly cracks unless they have been frozen most other cracks are repairable. T.
A flathead man told me if the block was a race or hotrod motor, or if you think it may have been, look closely at the center main bearing web area for cracks. High RPM and stroker cranks sometimes proved too much for them.
