Are you running open breathers on the VCs? Also, perhaps you want to consider grabbing some composite VCs if it bugs you enough.

eh. this is motor number 4 or 5 thats had some type of heads/cam etc on it, never noticed this much valvetrain noise except for when my impala ate 3 valve tips.

so switched to 10w30, quieted valvetrain down when hot. Did drill mod to tb to stop split blm's and get iac counts to settle at about 40 hot. sent out for a tune this time, but car is really rich everywhere, especially idle. I gotta double check fuel pressure.

May want to send injectors out for cleaning too

meh. screw it. rich is better than lean

I had them cleaned when I originally got them

did you double check the part number that they were 32lb? because after taking 20% fuel out of the tune i searched the part number and they are 37lb
