Check list for plenum repair

I'm going to start buying the gaskets and then the plenum plate on ebay for the plenum repair. However, do I have to buy new intake manifold bolts? I see them on advanced for like 30 bucks.

This is what I have in my list to get so far;
plenum plate (65 ish shipped)
throttle body gasket($2)
thermostat and gasket ($10)
plenum GASKET and intake manifold gaskets ($16)
the little elbow hose looking thing(advance's site doesnt have it so Ill get that from my work for around 5 bucks).
all gaskets are felpro.

the bolts are about 26 bolts so I'd like to reuse mine if thats okay?

my question is, how does that list look, and whats the reasoning people say to buy the bolts. And can i get by without them

I would replace all hoses and consider doing some preventative maintenance like the crank sensor. How are your valve cover gaskets looking? Replace those too if they are leaky. I used new bolts because I read that they are torque to yield and should only be used once. I'm not 100% on that but I didn't want to take any chances. It's actually cheaper to just buy the hughes kit but I pieced mine together too. Get some degreaser, new hose clamps, and wire brushes. I did not use the front and rear intake gaskets. I used permatex in the squirt can and made a thick bead where they would go then waited about half hour before I installed the intake. Worked great.

intake bolts are one time use only. get the intake manifold bolts.
the plate bolts won't be long enough for an aluminum plate iirc.

okay I will get the new bolts. I know the hughes is cheaper, but i read they use chinese gaskets.

I am going to get a degreaser, to clean the intake. And ill get an assortment of hose clamps.

I'm also going to get a new oil filter and 5 quarts of oil.

Just go to the hughes engine site and pick up there kit it includes just about everything for it even the manifold bolts the cost isnt to bad the ebay plate is $60 shiped the say the bypass hose bolts and gaskets autozone price on there website is $50 so its already close to the same price as the hughes kit

Get the Felpro gaskets. That's what I did when I did mine. I'm pretty sure the Hughes kit comes with a new plate and the Dorman gasket kit. Dorman gaskets aren't necessarily bad, but they don't have a reputation like Felpro. The guy from thespeedfreaks.net (the same guy on eBay) gives you new bolts for the plate along with the plate. Also, after all my research, and I did a lot of it, I decided to reuse my intake bolts. I did the work quite a while ago and I haven't had any issues. Make sure you download the Hughes instructions though. It's got the torque specs and torquing pattern for the plate. You'll also need to get the torque specs and torquing pattern for the intake. I believe they're available as a link on the Hughes site (some dodge forum link). Lastly, throughout all that reading, I didn't see anything about replacing the thermostat when everything is off. Do that. It's a great opportunity to do some preventative maintenance.

Hughes switched their gaskets to Fel-pro the joke is on us. The gasket in the pic on their site looks exactly like the fel-pro I bought.

They should advertise that. Although, I feel better supporting the little guy that makes the plates and sells them on the side.

I bought my plenum plate here. Comes with the bolts, no gaskets. With the felpro kit, it ends up being the same price as the hughes kit. Plate is the same as well. Be prepared to break at least one bolt in removal. I would also buy some cans of mopar combustion cleaner to clear out all the oil and crud buildup in the manifold. Definitely buy new intake bolts, I broke 2 on removal plus they are one use. I paid $20 for a set at the dealer although I had to wait 2 days for them to come in.

I just got mine today. Bought it from that guy on ebay, but I contacted him through tsf (bought the gaskets seperate). How much time should I give myself to do this? While I was in there, I was planning on doing the cap and rotor, and the crank sensor, and I was also going to cut out the center divider in the intake (not the runners, though).

I want to say it took me about 5 or 6 hours for the whole job. I didn't run into any snags. I also did my valve cover gaskets in that time frame.

I took two days and scrubbed and cleaned the intake. Soaked it in de greaser overnight. Came out spotless. If you are cutting the divider it will take longer to do it right. There is a tremendous amount of cleaning from scraping the old gasket off the block and intake to vacuuming with the shop vac. You want to get all the crud out of there and if you are cutting you want to get all of the metal shavings out.

Working time was probably 8-10 hours for me, but I had 3 bolts break so that includes drilling, tapping and/or setting heli-coils. I also did a full tune-up and did the CCC procedure. Make sure to have a bunch of rags to protect the galley from gasket bits and such.
