Worth the effort?

Most if not all the time, gotta make room for the freak chance it isn't, but every v8 I have build 'quite a few' the cam timing is advanced beyond the advertised when just setting it dot to dot on the timing gears.

I have to always retard the cam to get it installed straight up tdc.

My 340 required 6* retard to get it 2* advance.
My 410 needed about 4-6* retarded as well to get it straight up '110*'

Now....hughes cams come with around 4*advance built into them, think about that.
