LOL, I love these threads. Viscious, thats the first I have seen that pic. Awesome (sorry dude), but you should have done it to the rest of the cylinders and sold it as a swirl ported head!!
Here are a couple from the same day.
End of my halfshaft coming through the inside bellhousing.
What the insides on my new tranny looked like ~500 miles.
Oil pan on the first motor I rebuilt (rings, brearings) after same 500 miles
P.S. I also ruined the head. Only thing to survive was the turbo.
