finishing up install taken forever got to the throttle body and realized that the cobra manifold has the exact same bolt pattern on back as the egr spacer. Does this mean i don't need the egr spacer? if not what size bolts should i run from the throotle body to the intake manifold because the stock double threads wont do it.

I believe the egr port is already part of the intake. And no, you won't need the egr plate. Just bolt that egr to the manifold now.

I just put one of those intakes on my car as well and since I have a whine noise coming from it... put on a 70 mm throttle body as well, no vaccuum leaks so unless the intake makes that noise i have no idea what it is?????

most likely it is the TB, I have a 65mm accufab on my Cobra, no noise at all

Some of the larger T bodys need a very small bleed hole drilled into the plate because the airflow through them mimics blowing acroos a bottle making the noise you describe. There is also a spacer available to put inbetween the IAC motor that gives you an air bleed adjustment that may get rid of your noise. I fail to remember the part number but it is a Ford service part.

bbk's make that whistle noise a lot. they're sand cast pieces. accufab's are billet i believe. i've yet to hear a accufab whistle. BUT DAMN ARE THEY EXPENSIVE!
