Break in question . burned paint?

Timing was 36 at 2200 rpm with vacuum advance removed and capped. cam specs. 244/252 @ .050”, 282/290 adv, .516”/.537” lift(1.5:1 rocker), 112 sep, .016”/.018” lash . Compression is consistent. Static compression is 10.3. . Trickflow 240 heads with 440 source 1.5 ratio valves. Only running outer springs on the valves. Ignition setup for now is a ready to run distributor with coil. When I install in the car, I will be putting on a super sniper with hyperspark coil and distributor but I do not have the fuel pump to run that on the stand. Carb is HOLLEY 0-80508SA 750CFM ALUMINUM VACUUM SECONDARY . Plugs are autolite 3924.. I do have a Mr. Gasket carb spacer, aluminum that I can put in. I am going install the inner springs and reset the valve lash, insert the spacer and give it a go. I know that the cheap ready to run distributor and coil are not going to cut it for high rpms but I figured that it would be enough for 2000-3000 on a run stand. Also, I just remembered that we did not adjust the air/fuel mixture at all. We just ran it OOB. Any help is much appreciated.
