    1.6 rockers and 7.800 rods

    After my new cam and springs I'm re-evaluating my valve train and going over everything, I did measure the push rods last winter and purchased 7.800 rods.

    Would my pattern be okay, its a little wide and possibly I could step down in size to get a slightly smaller wear pattern,

    I do plan to purchase a new set of Roller Rockers ( probably scorpions or comp golds ) and I would hope 1.6 of various brands are the same angle and so on.

    Unless I'm missing something, that pattern looks great as is. :cool:

    Looks good to me. On my OT truck pull engines we actually run a funky ratio rocker , so when the rocker is all the way down its in the center, but at the top it's slightly over the center

    I always thought my line was to wide, I do see many guys getting the line much thinner.

    When that band gets wider you will be making more H/P.

    Have to mention that it really looks like a lack of lubrication also. That's a really severe marking on the valve stem. Make sure you put assy lube on the again prior to setting the lash.

    Shouldn`t the valves be rotating if the geometry is correct?:confused:
