For a daily, this rr bottom hend and highport head with of course high port cams would make more hp in stock form than a highport itself in theory. It should also rev quicker. I have not done this myself but if your goal is to get the car running it should be just as much fun as before, if not more. As long as you don't sit at redline for a long time very often, less rotational mass= more power ie: underdrive pulleys and and lightweight flywheel.
