Any tips for removing stuck intake manifold? (Update...it worked)

Yeah there were a number of intake bolts that came up with oil on the threads...makes sense now. I'll be sure to do that. Thanks!

The best way to remove gasket material safely is to use a carbide scraper. They are very sharp, machined perfectly flat and safe on aluminum. They are available from most shop supply companies for about 30 bucks. They will remove the gasket residue without removing metal from the sealing surfaces. You will still see the gasket stain but thats all that it is remaining, just a stain left from the old gasket. upload_2017-1-5_21-21-51.png
