Good luck with it. The last 5.3 I messed with I had to Helicoil 3 bolts in one head. I have about 6 LS heads kicking around the shop and nearly all have bolts broken flush with the head. I got lucky on the 8.1. Every manifold stud except 1 pullled out with the nut and I put some CRC freezeoff on the one and worked it out.

Only 1 broken bolt on the drivers rear, going to weld a nut on it in the morning and get it out. Everything else worked like a champ. Spikes in the collector, yes. Hoping fitment is good. I noticed the pipes are extremely loose on the slip fit so I'll have to peck them down a little to get it it clamp down correctly.

The 99s injectors are MAXED OUT on a stock engine. After 99 GM had a mild cam change, better PCM tune, larger injectors and more power from the same engine.

19 lb/hr seems to stick out in my mind.
