1985 corvette tpi questions
 

I'm possibly buying an 85 vette tomorrow, all stock and nothing wrong with it. If I get it, I wanna put a bigger cam in it and probably some headers for now. What would be the best cam to use for a stock tpi? Also, is there anything else I would have to do? I've never really messed with the tpi motors just carbed ones haha. Thanks in advance!
