Understanding my timing....initial and total

So I've got my rebuilt 318 running. Running a Hughes whiplash cam and performer intake
on stock heads.
Initially I had it set at 15deg intial and total turned out to be 26. Idled fine, missing some on top end.
I dialed up total timing at 3000rpm to 35 deg. and initial came in at 25. (all with vac. disconnected). Runs better all around.
I was surprised to see I was at 25 initial. It's a stock dist. and modifications to springs and such will be a new to me.
She runs well with more torque set like this.
Should I search for more or tweak things differently?
