Would putting in dual valve springs + an i cam (assuming they are the same size journal) and swapping over just the i harness and sensors work for a higher rpm?
Or just dual valve springs + harness swap? Could the eta injectors keep up with the b25 redline?
Just some thoughts because looking back on the head swap, I just did it for higher redline when I had that car, and if it only cost some valve springs and the harness and a cps pulley that would be fresh for most people who don't like their eta because it redlines at 4500
