LS1 Cylinder head drawings for exh ports and bolts

Hi guys,
I'm building a turbo system for an LS1 using a single T66 turbo. I'm looking for a drawing of the LS1 cylinder head showing the dimensions of the exhaust ports and bolt holes so I can set up and machine the exhaust flanges for the turbo headers.
Does any one here know where I can get drawings of the cyl heads?
Thanks,
Wastegate

Yeah you can buy the flanges but I'm not sure if they are mild steel or stainless.

if theyre cheap, you could use them as an accurate template, assuming he cant find the drawings online.
