Doing some winter maintenance I finally got around to doing a compression test.
Cyl 1 192 psi
Cyl 2 191 psi
Cyl 3 193 psi
Cyl 4 191 psi
I also decided to actually check the valve lash. I trusted the shop that put the head together to check this out. Well this is what I get for doing that. I have also added the corresponding clearance to get to the low end of the factory spec.
Intake Exhaust
Cyl 1 - 1 .005 +.002 .014 -.003
Cyl 1 - 2 .006 +.001 .013 -.001
Cyl 2 - 1 .008 -.001 .015 -.004
Cyl 2 - 2 .010 -.003 .015 -.004
Cyl 3 - 1 .011 -.004 .010 +.001
Cyl 3 - 2 .010 -.003 .010 +.001
Cyl 4 - 1 .008 -.001 .017 -.006
Cyl 4 - 2 .010 -.003 .015 -.004
So I guess I'm going to get some practice at changing these shims. At this point I am thinking it might be easier just to go ahead and take the cams out. I can install my adjustable cam gears at the same time.

Watch it in 1080p
This is a RaceKeeper video / data display from the Dixie National tour this past weekend.
The car is running well. Going back to the 4.10's for this event looks like it was a bad choice. The 3.909's would have been the best choice for this course.
All in all the car is running well. I had a wheel speed sensor die at the event so we lost ABS and traction control...so that made the rest of the event "fun"
And here is the Go Pro Vid
