My credo
If you can't go through it or around it, then go over it.
whats the purpose?
 
Making sure it is installed correctly, mostly. That there are no errors in the sprocket keyways or pin. To a lesser extent, you can move the intake opening point around for tuning purposes if you have a multi-index sprocket.
 
The purpose is to make the valves open at the right time to make maximum horse power...

Hey long time no see BDAB, good seeing you!!!!:icon_thumby::D
 
yep, I am back, however I am not going to call anybody out anymore, no matter the nature of the personal attack ....... I am not even going to ask if somebody is retarded anymore...

It really depend on if you want to spend the time getting every thing set up for maximum performance but this is not necessary unless building a race motor...

kinda like clocking (indexing) spark plugs then?

Not really. The timing might be a few degrees off from the machining process, but unless you're squeezing everything you can out of the engine, it doesn't really matter. I guess it would if it's an interference engine, and even then it'd have to be fairly far out.

I just helped a friend put a new cam in his J10's 258. We never bothered degreeing it. Fired right up, broke it in, and has put a good 6000 miles on it since. No issues.
 
Helps to find true TDC. after cam change from stock grind to more aggresive grind.
