Not sure if everyone is following Richard Holdener of Engine Masters fame. Although he normally tests LS1s on the Dyno like everyone else on Youtube, he has a 2.2 Turbo he is working with.
He has already compared the old G head to the swirl head with some interesting results,

He also has David Vizard porting a head for him. DV is "the man" when it comes to porting, he worked in Formula 1 and has an incredible history of working magic. Can't wait to see that head on the Dyno, but I'm not sure if a DIY cold replicate what he does. This is part one of two:
Richard's first dyno run is here:
Note that he started without the Turbo, which was a precaution that paid off. He seems to have lost control of
the timing,it jumped to 55 degrees.
Some very odd results as you can see below.
Should be interesting! Best Regards, Philip
