LS1 oil pressure

[bowtie_nut]

I just installed an LS1 into my chevelle but I am not getting oil up to my heads. Before starting the motor I primed the engine through the plugged hole on the front drivers side. I am using a remote oil filter. It has a pressure gage on one of the ports of the remote filter. It shows that it has about 60psi. but no oil ever gets into the heads. I am concerned that I may not be getting oil anywhere.
