I'm beginning to wonder if it wasn't some FOD from a part of this screw:
or when my HG blew on #3 soon after I had put this head on last year. I was forced to drive 25 miles with the coolant temps constantly spiking above 220 and coolant leaking into #3...
It's odd it's only in #3, no other cylinders show any damage, you can see similar pitting in #4 in that photo above, but I'm pretty sure that was from the screw dancing around. The injector I put on #3 and #4 flow more fuel than #1 and #2 as well. Good thing I'm doing a coolant reroute, I'll just richen my tune slightly and stay conservative with my timing.

Brain, what's wrong with fattening up and pulling 1*? Its the labor I sympathize over. I haven't' touched the mechanical bits of my car with a wrench since the install.
