Adjusting rockers-valves??
excellent website with about 3 different methods. When I had hyd lifters I used the remote bump starter method, set my zero lash and 1/4 preload with the crappy CompR lifters. On the solid lifters I use the TDC (power stroker) method setting half, bump her around again to TDC exhaust stroke (I think) then set the other half, it's dead on with the solids.
