408 stroker head gasket recommendation

With the trick flow heads, they require the Harland Sharp Heavy-Duty Roller Rockers S72026K. I was trying to determine if simply blocking the holes is enough. Some have said so but I wanted another opinion.

The cam I am running is 286/294 duration (236/242 @ .050), with .544/541 lift, but running 1.6 rockers makes it .581/.578. The quench will be .020 plus head gasket thickness. If I run a .028 thickness head gasket it will be .048 but wondering if anyone has any recommendations on this application.
