I've just done a head and cam combo, and I've pretty got full bolt-ons. I'm looking to make 400+RWHP, and I've got 50k miles on the motor. Should I be concerned with the stock bearings?

I'm really kicking myself right now. I had a chance to rebuild the bottom end, but decided not to because I didn't have enough time. The motor was on a stand, the heads were off, the oil pan was off, the timing set was off, and now it's all back together again inside the car.
