Every bit of research I've done personally points to the 6 qt pan simply not being enough volume for hardcore road race stuff, especially on anything close to an R compound tire. Baffles and trap doors can only do their job if there's enough volume in the system to begin with. At the end of the day, you're still uncovering the pickup and although you didn't specifically state to this being the case, I'm assuming you see this most often on high speed sweepers?
If you're yanking the motor anyhow, I don't know if I would personally even bother with the 6qt pan. I'd go straight to the 9qt pan and I'd also plumb in an accusump.
