Ok, I got the engine out of the 89 integra (D16A1) and am gonna drop it at the machine shop to be rebuilt. I'm keepin the bottom end stock cuz I want it to last, but I'd like to put oversized valves, some cams with higher lift/duration (nothing extreme), and stiffer valve springs to match the cams. What would you guys recommend I buy for cams/valves/springs, and are adjustable cam gears worth the money? Thanks for any advice.
