340 Build- rocker questions

Looking for some incite and suggestions on going with 1.5 or 1.6 rockers to give a little extra lift to my current cam since I’ll be updating to speedmaster heads, 2.02/1.6 65cc port/polish, machine for larger pushrod/clearances to accommodate 1.6’s. Looking at using Hughes Engines rockers.

Planning to use .040 Felpro 1008 head gaskets
