I've nearly finished my cvh engine build in my group4 arched mk3 escort and I'm wondering what power it will run?

Also could someone tell me weather it's worth swapping to dcoe 45s and what fuel pump and reg is best

And what's the best ignition set up ?

My spec is
1600cvh ex race engine just refreshed by w-p-e
Rs turbo knife edged crank
Accrulite high comp pocketed pistons
Burton steel rods
Burton oil pump
Arp bolts
Uprated bearings
Baffled sump
Lightened and balanced
Stage 3 big valve head with massive inlets and extra port work
Newman race cam 3000rpm- 7500rpm
Newman double valve springs
Newman solid lifters
Newman vernier
Matched inlet
Twin 40dcnfs and pipercross one piece filter
Janspeed 4-2-1 manifold and system
Ultralite flywheel and ap racing clutch
Rs turbo breather kit

It used to have a comp ratio of mid 13s but it's been re cc'd and dropped to 11.4 for fast road use

So what ignition?
What power is possible on 40s and would you swap to 45s and what would it make on 45s

And can you get a modified dizzy for a cvh

Thanks
