Can we not re-use the old gaskets if they are in good condition and seal it with a little RTV around it ? I hope mine doesn't swell up as I have them soaked in carb cleaner.
I'm getting the metal gasket for the manifold to engine to be safe.

be very careful with razor blades.  Most razor blades are stainless steel, and that's harder than the aluminum manifolds.  You can easily gouge the aluminum manifold being careless with the razor blades.
Else, I've found those 3M "Scotchbrite" 2" discs with drill attachment actually work pretty well.  $20 for the kit?  I think Sears carries them.

I also use the 3M roloc products very good results, the discs come in 3 differnet grits. by color green is 50 grit, yellow s 80 grit and white is 120 grit. These are nylon bristle finger type surface prep disk. Most all parts store should have them.

So i've noticed.. I actually just finished up cleaning the manifolds off tonight.. A few little scratches and scrapes, but i actually found that using 220 grit sandpaper takes the really stubborn gasket off, as well as removing most of the scrapes..-Tesla

At the auto parts store u can get a spray can called or stuff called "gasket remover." Spray it on, let it sit a little while, then scrape off with a putty knife.
Don't get it on any paint! It takes it off INSTANTLY! (faster than brake fluid!)

You might consider, when you reinstall the parts, to leave all that rtv, adhesives, etc off and just install the gasket on the clean machined surfaces. Just a touch of a release agent lilke a smear of vaseline on the machined surface that will be llifted off. With two machined , clean surfaces and a gasket you should not need any glue, rtv etc. Just my 2 cents.

That's a good idea.
I've NEVER replaced an intake gasket on any of the engines that I've had to remove just the upper intake. I just use a light bead of RTV around the runner holes. Done this probably a dozen times with no ill effects.
On the other hand, if you're rebuilding the engine, then, duh, yes, go with all new gaskets.
