Did you use a jig and slot the gears?

Should the marks on the cam gears line up with each other like stock? Here is pick of mine done with the head shim installed. Dot on intake cam is is inline with arrows on the cam caps. The dot on the exhaust is towards the intake slightly. I only egged the holes on the intake side per specs. I have a video but can’t get it to upload.

Head shim makes chain effectively shorter which would move both gears counterclockwise. D on exhaust would go up and D on intake would go down. Opposite of what you have in your pic. But no they will not be lined up like stock unless both gears were slotted. From that angle it sure looks like exhaust is one tooth off. Move it one tooth counterclockwise and take another pic.

I would call Hurricane. I put a head shim on my viper but Dave supplied me with a timing jig and slotted sprockets.
