Just dropped off my Stang at Houston Performance to get the Speedline Racing Stock Ported Heads put in with a custom chip. My questions are:

1)Given the mods listed below, what rwhp am I looking at?
--SVO Blower (10lbs boost) and compliments, full exhuast, 4.10:1 gears, and every other mod except cams and internals

2)They mentioned at Houston Performance that they can get my cams regrinded for $400 total, is this worth it?

3)What performance gains will I be looking at with the cams?

4)Overall would the Regrind Cams be worth the $400 rwhp wise and are Regrinds in general a good chioce? I have heard bad things about regrinds!
Any and all suggestions are appreciated!!
Thanks everyone in advance.
