Need some help! LT Headers
#11
Your buddy is an idiot. Sorry but I have Mitchell and Alldata also and nothing anywhere say anything about lifting the engine to install headers.
Like others here, I have Pacesetter LTs and I did them myself in my driveway (literally) with hand tools. I did however spray them for about a week with PB Blaster.
I didnt bother to buy Stage 8 bolts but I did buy Grade 8 bolts and washers from Lowes
If you want to replace yours (which you will) then you need to buy (17) 8mm-1.25x25mm bolts

I had the same problem with my install... broken bolt on the manifold. took some time but its done. The 4.7 was yard to get to but with a lift was able to remove everything. Only trouble I had was the steering was rubbing on the header so I had to heat the pipe and bend it in a 1/8 inch to make clearance. My side pipes are plenty powerful and loud rumble with dual flowmaster 44's . Good luck

I always use an impact on rusty bolts. Its much less likely to snap a bolt than hand tools. Here's another thing you can try, Heat the area around the bolt with a propane torch, and touch a candle to the threads. The wax will be sucked into the opening around the threads, and the bolt can be removed easily. The heating and candle application may have to be repeated a couple times. This works on the same principle as "sweat-soldering" copper pipes, and will work where penetrating oil will not
