Default Swapping out #537441 for Butler 067

Previous owner rebuilt the 350 30 over with 4X small vale 96 heads - but can't for life of me understand WHY they put this peanut cam #537441 grind in it....had decent torque off idle but nosed over at 2600 rpm....and 4 barrel was worthless...hence this swap.

Got the Butler 067 to swap out and hoping for more top end. Anyone been here before, any advice? With 7.6 compression, I'm thinking 067 is about as big as it can handle.

It's as father son project.
