No the 3/8 on their website is the ft lbs one.. The inch lbs one is the smaller 1/4 one sadly.. Just get an adapter from advance auto parts for $3, and youll need a 6 inch extension as well obviously. As i said about the clicking it doesnt really click until your at like 100 inch lbs + so just go slowely when tightening and use your fingers to tighten it not your hand/arm strength and watch the arm when it clicks inward thats the "click".. Just start at 20 inch lbs, then go to 24, then 36-48 and so forth..
You do have the torque sequences right ? Get a sharpie and mark your pan like the TSB shows you for each bolt so you know which one is bolts 1 -2 -3 -4 ect.. Or just print out the papers and do it. Also when you torque down the main intake bolts use some black rtv on the threads because supposedly oil can get through the threads and go up and on your engine. And toss those rubber gaskets that you put on the front and back of the manifold.. Use A TON of rtv in their place.. well thats what i did anyway some people use the rubber gaskets and rtv together.. I also put a very thin amount like paper thin amount of rtv on both sides of the intake gasket where the water jackets are.. I read pretty much everywhere online for any car that this is a good thing to do... Ratmonkey disagree's.. but i did it anyway.. Dont use RTV on the exhaust and intake holes, and dont use any rtv on the pan gasket.. rtv is bad for the engine and 02 sensors. You also might want to purchase a cheap shop vaccume from kmart or sears for $30.. Trust me eve tho you put rags in the lifter gally you will get dirt, old gasket, and **** inside there so you need to vaccume it up.. and also get 5 quarts of cheapo walmart oil because coolant will get into the engine.. so drain it when your done and fill it with the cheap oil and drive it around for a bit then drain it again and fill with your normal oil.
Oh and dont use any kind of paper in the coolant jackets (to keep dirt from getting in them) use an old rag.. I use news paper not thinking it would turn to pulp and i couldnt get it out and while trying i pushed it into my heads.. I had to block the holes and put my mouth on one and blow hard to push the pulp blob out.. lol MMM what else... oh and when your done i would make a oil catch can for the pcv valve.. Go to lowes.. go to the tool section and purchase one of those air compressor filters for $25 or was it $35 i forgot.. Remove the 5 micron filter from it, and go to the dollar store and get some of those metal scrub pad things and stuff the plastic tube with them.. and use rtv on the hole on the bottom of the tube to block it up so air doesnt get sucked through it.. Then get like 3 feet of fuel line tubing and some zip ties and hook it up to your pcv system... This is how much oil my catch can caught after only 4 days thats like 1-2 teespoons right there.. I did this because i noticed after i fixed my intake i looked inside and it was getting oily getting.. youd be amazed hwo much oil gets in there from the pcv..
Oh and I suggest you get a try and lable the bolts you remove like alternator, a/c compressor ect and also i would take a picture of each bolt you remove and its hole because some are long some are short and i garuntee you will forget which long bolt goes where and which short goes where.. Get felpro intake gaskets, and i suggest you get a new thermostat, new thermostat housing, new thermostat gasket, and new throttlebody gasket as well.. and a new upper radiator hose and the small 3 inch hose between the waterpump and intake manifold.. Trust me on this. They dont sell 5.9 upper radiator hoses just get the 5.2 and cut the hose for your low speed fan sensor thingy
