I got a set of usdm cams a while ago and I wanted to put them into my jdm aristo motor . I know that they arent the sickest choice but I have them now so I figure why not just put them in before I put the motor in the car. Problem is Im useless with the whole shim design and how to measure lash. Has anyone done the same swap around here? the supraforums search function is down and I was hoping to swap them in this weekend.
