Help spec'ing out a new small block

Cam - Solid Roller .660 lift, 254/268 duration @ .050 and 108 lobe center. Decent specs, could be bigger but probably perfect for these heads.
Nice street beast cam IMO A similar cam was used with a set of Victors where Miller ported them. I forget the displacement, but it was around 370. The Victors allowed impressively good power with a small cam like that. It was an engine masters entry IIRC.

This alone shows exactly what I say, get the best head you can up top! The tunnel ram also help.
12.5:1 CR
977ish billet 4150 from Dominic Thumper
5800 stall (flashed right at 5750 on the chassis dyno) 9" PTC non-lockup converter. Probably too much stall in my opinion but we will know for sure once it goes down the track.
Spooled 4.30's on a 29x10.50 Hoosier Drag Slick with stiff sidewalls.
If this all works now, changing the camshaft will effect it a lot. You know the drill.
408ci which is as big as I would go with this block.
Out of the box Trick Flow cnc heads and Track Heat intake (blueprinted on install)
IDK if a TF head has what it takes. As in how far it can be ported.

Hedman Hustler 1 7/8 primaries and 3.5" collector running through 3" mandrel bent duals with x-pipe and Dynomax UltraFlow SS welded mufflers.
Good, not great. A lot depends ultimately on the total HP made.
