Your oil pressure seems low...you should be right around 60 psi at 3000rpm. What weight oil are you using? And did you make sure your injector o-rings were installed properly? Gas in the oil can cause low pressure.
Also...why did you delete the exhaust manifold heat shields? Things get hot enough as it is...I would have installed them.
And I noticed you're missing the .008" step in your flywheel. This may cause premature clutch failure.
