TH400 - Who has the best off the shelf rebuild kit?

[Joxracing]

Looking to purchase a rebuild kit and reverse manual valve body w/ engine braking for our Super Stock Truck (short course off road) We make about 330ish hp & 350ish torque through our small block.
Im looking for the best "off the shelf" rebuild kit and valve body. We don't put much power down but the transmissions do take a good beating.

Thanks in advanced!

Trans Go makes a cheap manual valve body kit that works well $45
