A lot. Do a search. Plenty of information on what you just asked.

About 15cfm in most cases and not worth the extra money on the headers IMO! There are way too many affordable aftermarket heads dont bother!

Pending you budget and c/i you can get some respectable numbers from them but money to money you lost out!
