    I got some yella terras at KY Speed for $409.Is that the correct stock ratio? Most people just up grade with better bearing from harland sharp or compcam.consider getting a push rod checker,and you mite need better push rods if you are changing the ratio.Have you been to the GTO forum ?

    the ls motors are notorious for valve train noise,my 99 silverado sounds like a diesel when its cold,im still using the stock GM rockers,rev mine to 7800 in the GTO,its also alil loud,at idle when cold. dont think the noise is the rockers, rather think its the stock lifters,GM has upgraded those and they have gotten better.
