I have a 305 in my El Camino. I am going to install a set of shorty headers. It looks like they will go in OK. The only issue I see is the oil sending unit on the left side of the block just above the oil filter. It sticks out about 3" and appears to occupy some of the area that the header collector will have to past through. If this unit is in the way, what would be my options? I believe this unit sends the oil pressure signal to the oil pressure gauge.
