105 H.P. is more than do-able if the engine is assembled properly, ( ie; proper deack height / combustion chamber volume )
and of corse proper head preparationand tuning....
1.1 Ratio rockers are stock ratio. perfect or an engle 110 cam, you can push the RPM a little higher with 1.25 Ratio rockers.
The 40mm carbs are the best choice here with a SVDA distributor ( not a 009 )
Unless you have the new AA thich wall 92mm pistons, be aware that the regular AA's and the Cima 92mm Barrels have the thinnest wall and are prone to overheat warpage. ( not the best choice for a daily driver )
