I built mine, 11.7:1, flat face valves, and .027" HG with these cams. I have yet to start it, I finally pulled it to take it to a local shop that is now sponosring the car, they are gonna find out what is wrong with it.
My car threw no codes at all on my Kpro also. I did have it start on the third try, it ran like shit for 5 minutes, then got to 245* and I shut it off, then after 3-4 minutes I heard a pressure release from back of block, then nothing. I cant get car to start again. I did a compression check, which I recommend you doing, #1 and 4 were 40psi, and #2 and 3 were 65psi, oil in the cylinders bumped all 4 exactly 25psi higher.
Also, what is your valve lash set at? Specs say intake at .006" and exhaust at .008". I would check the clearances, if too tight your car wont start cause valves wont close properly to build compression. Also, try setting them loose like .008" In and .010" Ex to just run the cams in, then go back and tighten them to specs. That way you know they are opening/clsing correctly.
All else fails, talk with your shop again, which hopefully you are doing already anyways, I bet they are willing to help.
