Hi i just got the new lash pads for my camshaft setup, but the don't fit right. The old ones have the hole in the bottom where the valve head fits in them. The new ones are flat. I ordered them from the nissan motorsports site. Anyways, what do i need to do to make them work. With the adjuster all the way down the rocker arm is still under a little bit of pressure. This is an e31 head. The adjusters have the thick nuts that lock them in place. I got the .25 lash pad set. I have a 555lift 300deg. duration cam shaft. they recomended the slightly thicker one for a 560-580 camshaft so these should have worked just fine. So whats the deal
