Thanks for that. It looks like they ran a bunch of different cams or no one knows what they ran. The specs on the TF cam are posted as 234°/247°@ .050" .600"/.600" (1.7:1 rockers?) 108°LSA. It does look like they stepped up on the heads regardless of the minor differences in cam specs. Now to scope for some more detailed results from the builders that still grace us with their presence.
