W2 Heads
Hi rumblefish360. Thanks for those numbers, yea they look familiar-ish. : ) I have no idea what differences existed on the 2 benches. The "Evans" numbers were given to me when I bought the heads. The "Rob" numbers were done by a friend for me as he had access to a flow bench in a machine shop. I wasn't able to witness either setup. But I am glad to have some data since these were ported.
