2eighTZ4me Posted September 2, 2008 Author Share Posted September 2, 2008 Those shims were put under there for a reason. Everything you described was done already. Those shims are to bring the spring seat pressure to within spec (with the Racer Brown retainers). I got the cam card that came with the Racer Brown cam and brought it to my machinist and he setup the spring pressures and installed heights exactly to what was recommended. I have since removed the stock retainers and gone back with the Racer Brown retainers after taking the Dremel to them to widen them out just a hair to accept the factory Nissan lash pads. Installed height is back to spec, as is spring pressure. I still have an issue with two rockers' wipe patterns, but will be ordering correct lash pads today to correct. I think I'm (finally!) in good shape. Thank you guys for ALL your help! Quote Link to comment Share on other sites More sharing options...
