you have 4 pages of suggestions , im not going to read all that , im thinking clogged cat

i would guess they are the same , they go on either side and do the same exact job ,

check your grounds

i agree , bad head gasket , it is not blown yet , but if not taken care of , it will get worse, those sealer products may work , but only a temp fix, my advise is do it right once

there are online places that sell you that information , i think they charge 5.00 for two build sheets, i found them through the GMT-400 forum

did you put oil on bolt threads , and under head washer , that helps even out the torque

it's easy to remove , just a vent hose on back , check it for being clogged,

i would start checking wrecking yards

if you look at your haynes manual , chapter 2a, page 2a-2 specifications , middle of that page has torque specs for exhaust manifolds

according to alldata , 2 passes 11ftlb first pass , second pass 22 ftlb flange stud nut 47 ftlb

i would check wrecking yards, probably in the south , as they last longer and still around

do you have the correct tire size , has rear diff been changed , if not speedo should be with in 5 mph of actual , mine runs 3-4 miles slow

same year same cluster

this is just my opinion , based on almost logic , the engine should not start and run , because the computer controls the whole truck engine , transmission , everything , no computer no start or run

i would go on line and compare lift kits for both see if they are the same , i think that is your best option
