Small block + 4 speed build

I did not mention earlier on that 360 block is a magnum block and i am not experienced with these things at all. I got Harland Sharp 1.6 ratio rockers dedicated for magnums with pushrod oiling.
Also intake and carb finally got here with timing set and other smaller parts.
Someone locally offered me Hughes magnum hyd roller cam with their performance lifters option which is smaller than I initially planned, but not terrible.
Spec is 238/[email protected]” 109lsa, 104 intake centerline. This will be .578’/.587” lift with my rockers.
Thinking of I should pull the trigger on this.
