Default Camshaft Degree Question for Pastry, Paul Carter, whoever..... Voodoo 704

Good morning, we are currently degreeing the camshaft in the 467 we are building, it is the Voodoo 704. Compression is right at 9.35-1. We installed it dot-dot with the Cloyes 9-keyway bullet set first to check it, and it came in at 107.625° Intake Centerline. We then moved the crankshaft gear to the "2A" keyway and rechecked, it came in at 105°. We haven't tried advancing anymore yet. If we move the crank gear to the "4A" keyway, and it moves the camshaft close to the same amount as it did with the "2A" keyway, in theory, it would move it down to 102.5-103° Intake Centerline. My question to you is, would you leave it at 105°, or would you advance it more, even if it came out down at 102.5-103°? I checked the lift at TDC on the Intake and Exhaust lobe, and if I measure it correctly, the Intake is open about .089", while the exhaust is only open about .067", so the Intake lift is only about .022" higher than the exhaust with it at 105° Intake Centerline.

Thanks!
