I was offered my cam in 108 or 110. I did 110.
It was ground with 4 degrees in it. With one chain was perfect when checked. No need to use offset keys or multiple key way gears. Got lucky
Another same cam close in size had to use the multi key chain and gears ground at diff time. All motor have variables everything must be checked to get the most you can out them.
And my very last custom was this solid degred easy with multi key gear set
