What I did was blue the pushrods and then install them in cylinder #1 and spin the motor with the plugs out using the starter. You have to be very careful installing and removing though as you can nick the blue and it will look as if there is a contact issue.

update, put a cam in with lsl lobes and the noise is gone. The only change was the cam, everything else is the same.

previous lobes were xer, I had two other cams, both with xer lobes and no matter what I did they were both the same. Plus this one is making way, way more power. It is just unreal how different the car is.

My old 222/238 XER was very noisy too.
