I would advise against pulling any stock GM intake apart (LS1, LS2 or LS6). They are "sonically welded" not glued. And if you were able to pull it apart you'd never get it back together and sealed. It will leak like crazy. The FAST intakes come in 3 parts and are designed to be ported, as for the stockers, the porters use very long bits to do their work.

If you want to take apart a stock intake, you need to cut the bottom out like this (see pic), then, if it has tower braces, as does the Ls2 intake, those need to be removed. Then you must find high temp. epoxy that will bond w/nylon & trumpet the intake runners like this (see pic & again relates to an LS2), then smooth. You can also sand the oulet of the runners; the end that meets the head. After completing the work, the bottom needs to be welded back on w/ a plastics welder (rod compatible w/nylon). After welding, cover weld w/ high temp silicon & you're done.

couldnt i use fusor to hold it back together?????
if it can be sanded painted grinded molded and everything else i dont see why i couldnt
and heat shouldt be an issue considering u can bake it

Try what you wish. However, I can tell you from experience that nothing tried, short of welding w/nylon compatible rod held the bottom on once it was under the engine's vaccum pressure. Now, if you want to nearly **** your pants when it goes POP after a few seconds of running, the first time you fire it up, then by all means try to hold the bottom on w/ adhesive. I don't know what fusor is, but, tried several different methods & nothing short of welding held her together. Also, it is likely that whatever was used by GM to hold it together probably has the same heat toloerance as the nylon. So, the manifold may melt w/ the adhesive if you try heating.

well you can use fusor panel bond to hold on quarter panels if prepped right the metal will ripp before the fusor lets go
the fusor plastic repair if prepped right should work its just as strong as the panel bond
well i can plastic weld if it needs to be

Why not give it a try? My opinion about the fusor was based upon not knowing what it was. Maybe you have found an adhesive that will stand up to the heat & vacuum @ the intake. If it works, then it will be an advantage for those not willing or able to weld the intake back together.

well welding it is no problem i just think fusor would be 100 times easier so i have no ideal what i need to do in the inside what exactly am i trying to smooth out?

You need to cut the three support towers out (remove them), then trumpet the inlets as in my pics. Trumpet means to make a smooth trumpet shape surrounding each runner opening. All of the yellow colored stuff in my manifold is added epoxy, used to do what I have described.
