Have you tried porting and polishing both the head and manifold exhaust ports? A slight misalignment could be causing a restriction or higher than normal back pressure to develop resulting in improper scavanging of the cylinders. This would leave a higher than normal level of exhaust gases to mix with the incoming fuel/air causing a lean mixture and possibly misfiring. When rpm's increase, exhaust gas velocity increases allowing for proper cylinder scavanging and the miss goes away. It's a theory anyway.
