isnt extrude honing where they force abrasive material into the runners and whatnot to open them up a little bit? if that's the case, take it somewhere because you're going to mess it up

Yes, extruding/honing is were a putty is forced through at high temperature and pressure to smooth and enlarge the internal passages. I have never herd of a way to DIY this. You can however do a DIY port and polish. IN which case you can pick up a DIY port/polish kit from SummitRacing/JEGS or piece togather your own bits.

port/ polish is what im interested in then...i dont want to take it anywhere i got no money hahaha...and i have the tools to do it im just looking for some tips or procedures...and what about the injectors and torques?

03blackrt · Post by **03blackrt** » Fri May 11, 2007 6:38 pm

The injectors pop in and out. Little rubber o-rings hold them in along with the fuel rail (which has two bolt that hold it to the manifold and a clip that hold each injector to the rail)

The intake manifold to cylinder head bolts are torqued to 105 in*lbs (12 N*M)

Tips would be to start out with gasket matching the cylinder head-runners gasket and the plenum-runners gasket. Removing the "injector humps" is good too. You can cut off the ram pipe on the plenum and weld on a 2.5" pipe for better flow too.

Thanks man! big help

105 ft-lb seems like a bit much though....

sweet...hey! what about the header...is it the same procedure and same torque?

03blackrt · Post by **03blackrt** » Mon May 14, 2007 11:25 pm

The magnum header-to-head bolts are 200 in*lb or 16.6 ft*lb

just one more question....gaskets r good to re-use right? and thanks for all ur help man

t vago · Post by **t vago** » Tue May 15, 2007 12:34 pm

Eh... Not so much.

Why not spend the extra $4 and get a 4648623AB from your local Chrysler parts counter?

The two magnum intake mani gaskets are a composite material, they may fall apart when removing. I have glued them back togather before, but I wouldn't reccomend it unless your good at gluing

The magnum exhaust gasket is stainless steel (or some other metal). Usually it remains good. But I'd go and get new gaskets so you don't leave yourself stranded with no gaskets and have to wait a few days to get them from a parts place, but thats just me.

Oh yah... if you separated the upper and lower intake, you'll want to spend another $9 to get a 4884067AB gasket from your local dealership.

An make sure you order the Magnum part numbers T vago posted, cause the regular intake manifold uses rubber o-rings as a gasket and a crushed aluminum exhaust gasket.

so the header gasket is good to re-use and the intake is a big fat no...got it....anyways thanks for ur help guys!
