Hello Members   I had Oregon Cams  grind a  S/C ( 2063) cam for me.   .224 In , .226 Ex at ..050.  Lift In .293 Ex ..295 112 lobe separation.  They call for a .016 valve clearance both In and Ex.  Fords EDB 6250-e  high lift cam (In fords cookbook S/C  manual)  calls for hot lash  .020 In .025 Ex. Anyone explain which one to use?  Also manual  states specs for  both standard cam and high lift.  Was thinking only the EDB high lift cam was available in S/C engine.  Cos  Oregon

Use the cam card specifications.  Your lift with a 1.54 rocker arm is still only in the .454" lift, and with 1.6 rocker arms .472" which is not an issue for piston to valve clearance or cylinder wall clearance.   Joe-JDC
