Exhaust flange dimensions on LS1
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

How about using GM's own LS1 header flanges? Check out PN 12480130. Less than $20 at Scoggin-Dickey. I think I'm going to use these for my custom LS1 headers.
Edit: Or try these guys: http://www.schoenfeldheaders.com/sbflanges.htm
$24 each.
