.002" difference is not a significant number on any cam profile. The HP cam is so mild it won't be noticed at all either way.
.002" looser will give you a little more torque. .002 tighter a little more rpm. Neither significant at all.
If you hear a little more ruckus in the exhausts almost like a pinging, sometimes like a spitting sound, you're too tight and best back off a little, less you burn the seats.
On the intakes, if you are too tight, you will have the tendency to flame out or backfire through the intake at idle.
Of course if you guys want to debate how many angels can fit on the head of a pin, carry on. You are all doing a superb job of it.
