Went to the track, dissapointed

are you 1000% sure the ports are not misaligned when its bolted up? if you smooth the intake too much you screw up the boundery layer. some of the best engine builders on the planet will tell you that gasket makers arent port designers.

a good way to figure out if the lower is screwed is to put an OOTB lower back on it.

the NHRA correction factor for 1900' corrects that 13.60@103 to 13.30@105.3 at sea level.
