Default looking for L27 valve/camshaft specs.

i've been playing around in my cheap arse dyno program, trying to build an L27, then tweak things and see what happens. just looking for some of the important details to try and make it accurate. it'* a cheap little program so i'm not expecting a whole lot. but it'd be nice to have some idea whats going on.

anywhere here is what i need.

the lift, duration and lobe seperation of the stock camshaft L27, Vin 1 L67 (if different)

intake and exhaust valve diameter

and flow of the stock TB in CFMs

i don't know if this information is out there, but i wasn't able to find it. i hope i posted this in the right place. thanks for the help.
