So bring it up to 1.6 from 1.5 on intake might be a idea.
So are you replacing the std rings doing so ?
Its 0.05” radially open up.
I has little hard to beleive its worth it as this ports is not ideal.
I guess the port work is more important than inlet area on valve.
But I cant tell as no experiance.
All I know my bock is really way bigger than std.
What get me worry is 1 cylinder has a crack welded up, its really nice done and comes from the exhaust port ( classic crack place )

I heard a Bonneville no blower not bored over or stroked and both at 1.6” really pirted up and tri-Y headers and .520” roller cam made 400 HP at sealeval.
Sounds tuff but car was fast.
If I go over and get my carbs to Uncle Max I hope visit him talk FH.
