the cause of the low rpm miss was a broken exhaust valve spring,car runs like a charm once again

Now you need to figure out the cause of the broken spring, if you don't the next one could take out the whole engine.

It is possible for a broken spring to leave you with little left but one head(the other side) and the intake for good parts.


Possible it was just a freak failure but you still need to investigate further. Are the springs really appropriate for the cam? How old are they? Are they setup right?

the engine was complety redone with forged internals,but the comp cam and hi-crane roller rocker lifters was installed,we did change the cam bearings,but the springs,i dont know if they are the original stock which would have 128,00 miles on them.or what.
