great i've considered the ms3 but when you see the hp difference and videos like this http://videos.streetfire.net/video/B...-01_197493.htm , it really makes me not want to be the guy with the ms3, 30 miles a day to and from work and most of it's hwy crusing at 70mph i don't think i'll be that annouyed with the ms4

If they clear, I would get the cam and do the N20 later.
you do not have to flycut with stock valves.. when you do get aftermarket heads they have to have stock valves also, or you must flycut.. i am not cut, and i ran stock heads and not PRCls6 heads still not cut..

!!!! if you pick the ms4 over the ms3 for only that reason you are WAAAAAY off... the difference between the ms4 and ms3 is MINIMAL to non existent.. you are talking 2-7rwhp MAX.. track times, depending on the rest of your setup could be better with either given cam... in the same car same day the ms3 MIGHT just MIGHT be .01 slower.. if thats enough to matter.... you are a hardcore racer..

seriously call TSP and ask them how much more power and how much faster you will be with the ms4 over the ms3...
