I responded to most of your question in the Farmall B section, but let me add what I know about Texas. The pulls I've been to in Texas were using either EDGE&TA (Early Day Gas Engine & Tractor Ass'n) or NATPA (National Antique Tractor Pullers Ass'n) rules or some variation thereof. The EDGE&TA rules are more restrictive in terms of modifications--basically they require that you don't stray much from the stock form of the tractor. I would say most of the pullers I've seen didn't have wheelie bars.
Hope this helps.
