Honda kseries cam degree card question

I’ve got a set of skunk 2 tuner 2 cams for a k20/24 I’m building I’m trying to figure out opening and closing times so I can properly degree in the exhaust cam the intake still uses the vtc system the spec sheet only gives me a centerline of 107degrees and gives me peak lift specs but no opening and closing specs I’m assuming they want me to use the centerline method to degree the cam in but I would like to know if I can do it the way hpa teaches you so I know it’s correct due to the fact it could be off slighly using centerline method

Any info could help thank you

Unfortunately it's not uncommon for some cam manufacturers to give very limited data to work from. In this instance you may need to accept that and work on the centreline method. This will likely get you very close anyway and if you're intending to further refine the cam timing on a dyno then it really won't be the end of the world.
