65 Chevy c10 questions

[Jake65]

Im 16 and have some questions and could use some assistance. In the 4 speed top loader on the back of a 292, how do you remove the shifter from the tranny? Me and dad think that we have an idea how but we'd like to hear it from someone who can verify our thought. My other question is, can you use the stock intake for a 292 and still run headers? Anything will be helpful. May post pics of both soon for a visual reference.
