help Rocker arms question

[tonizzos]

hi, we have a problem with the final tuning of my engine

i have a 2.0T engine and we did the 2.2S P&C upgrade with also 2.2-2.4 heads
i bought E cams and now we have a problem tuning the rocker arms.......
it looks like if the srew of the rocker arm is to short to tune it for the exhaust valve !!

i do not remember having seen something writen about a change to do to the rocker arms for this upgrade ...

any ideas ???

cheers

Were these reground cams? If so then the base circle is reduced-or the stem height
of the valves is short. There used to be cheapo cams out there that had a too small
base circle. Not really safe to use as it throws the geometry off.

I bought the cams from a member who swapped them for others and they run well in his car.. So would say cams are ok....

My mechanics says he would need 5mm more on the exhaust valve.... Could it be that the valve is to short? I bought the heads with new valves put in place...

5mm is a lot
You could use lashcaps.

I assume the rocker arms were ground/resurfaced? Could it be that too much was taken off the pads?

Thanks friends, we took a Head out and checked !!! The exhaust valve is 6mm to short...... So ordered 6 new ones

Thanks to all for the help
