The cam card says installed center line 104 degrees. Install dot to dot, and check with degree wheel, and dial indicator. If the intake lobe center line is not at 104, adjust with a multi key crank sprocket, or a offset cam bushing.
In a perfect world, installed dot to dot, you'd be at 104 ICL. But it's not perfect. Do like @Charrlie_S said. install dot to dot. Wheel it. See where it is. Adjust as necessary.
And here's the thing. Most cam companies are VERY proprietary regarding any advance they "grind into" a camshaft. I've found more often than not, you get a shitty answer when asking that question.......ESPECIALLY with Hughes. I basically got the same thing years ago when I asked the same question. Basically a "shut up and do what we say" kinda answer. You can just imagine "MY" response. LMAO
