I have a set of 1.54 rockers that would be good to install.  What is the minimum?  Dont recall exactly the clearance figure with the 1.43s before assembly.  The high ratios could be put in place with zero lash for a rollover check.  If no interference occured at least there would be the .017 margin.  Heads milled .035, decked .028, 1.93 intakes, Isky E-4 with .017 lash setting, flattops.
