degreeing a slant camshaft with no cam card

At this point I am fooling with stock engines with as far as I know stock cams.

I have two un-touched ( as far as I know ) slants, I pulled a second one out tonight and set it up in my workshop on the engine stand.

My plan is to degree both engines and compare the readings I will be getting between the two.

I am convinced at this point that the standard for measurement on these engine is as mentioned @ .006 lift and am hoping to confirm that with the second engine this weekend.

Alot of what you guys have said above is starting to make sense too me but there is also alot that I still do not understand so I will keep working at it and ask questions.

I read alot about the degreeing process and some like the centerline method and some like the @.050 method.

This has me confused a bit.

If I know the standard in which my cam was measured ( @ .006 ) and I can measure intake opening and closing points using this standard than what other measurements and I trying to accomplish and why?

I hope this does not make me sound lazy or as a slouch. I would like to take any opportunity I can to learn anything I can but I am un-clear of what else I am trying to accomplish I guess.

Isnt the timing of the valves opening and closing all we need to know? What else is there and why are they important?

If we know the standard of measurement ( Like I think I do ) than what else is there to accomplish?

Why do I want to know my intakes and exhaust valve centerline as an example?

Yes I plan to up-grade to a more suitable cam eventually for my truck so Im going to guess that all these other measurements that I still need to learn how to make will help me to better understand what might be a better cam to choose.

This has got to be an answer to my own question I suppose.

Thanks
