Definitely better advice.If you can't get that bolt out STOP! Pull the manifold and take it to a machine shop that has a milling machine. They can clamp it to the table and center it up over that bolt and cut it out with an end mill,tap and install a tread insert or(yuck!)helicoil.
As I said that intake is pricey. Currently the Edelbrock 3704 TBI intake is $500.
