Well, my headers will be here next Thursday so I figured I'd go out and shoot the manifold bolts on my 99 Sierra with PB Blaster this afternoon. Spray the passenger side bolts first, spray the drivers side second, get to the very last bolt (in the back) and the head is MIA. What are the odds that it A. Fell out or B. Didn't break off flush with the head?

 

slim to none!!!!

 

Thats what I figured. Looks like I'll be spending some time getting the dang thing out I guess. Maybe these Sundays of going to church will pay off and I'll have something to grab on to

 

I got lucky 3 times on the same head, used my vise grips and some heat and they came right out.

 

Mine fell out.... Could get lucky!!! There is hope.... What headers you get???

 

I ordered the Speed Engineering 1 3/4" headers with ORY. Checked this morning with a stubby screwdriver. Bolt is definitely broken off flush with the cylinder head.... looks like I'll be pulling out my welder for this one

 

Sorry to hear that....it sucks good luck with it!!!

 

Thats the way it goes sometimes! Next thing will be a BTR Stage 3 truck cam, and I'll have to order injectors being my truck is a 99. Still have no clue what injectors to get though.

 

8.1 marine injectors maybe???

 

Honestly thays what I'm guessing, I'm clueless when it comes to injector sizes and whatnot. I've drag raced my whole life, know the LS scene fairly well, but this is one thing I'm not familiar with. I'll get with my tuner and have him tell me what to buy lol! I've got a 6 liter on the stand I'm building but want to play around with the 5.3 first.
