Opinions wanted: 408/416 Stroker or 440?

I went the stroked 340 route and it's now at a 418 (.04 over)
I used w2 heads and custom cam from Lunati.
430 rear gears and passon 4 spd od gearset
It makes me swallow my Adams apple when I dump the clutch

I honestly debate switching to a stroked 400 and hit 451 and upgrade to 440 source heads.

The 400 block is a lower deck and easier to stuff between fenders for exhaust reasons.
