Edelbrock RPM cylinder head (60779)

I like those "Gunships!"
What's the braided line to/for?

got them with a bunch of parts we bought..... stupid things list for $350 :wack: Ran them on our W5 mills..... just a wall decoration now.

Block was filled. We had additional cooling from the timing cover to the side of the block. We drilled the filler to flow to the center of the heads.
