Looks factory! Be prepared for the servo to only work intermittently if you fit a performance cam, as duration increases vacuum drops off sharply.
It's no big deal, as no doubt you know a servo doesn't make your brakes any better it just lessens pedal effort. You can mitigate that to a certain extent by binning the servo and fitting a master cylinder of a different bore size. I'm not convinced by what I've read about Vacuum tanks and electric vacuum pumps being a good solution. Diesel Transits and no doubt other stuff use a vacuum pump driven off the back of the alternator which might do the trick. Me, I've been binning power steering and power brakes off my cars for the last 30 odd years...

unless you're going with quite a lairy cam i wouldn't worry about vacuum loss. most mild cams have little if any noticeable effect on the brakes. what cam were you planning on using in the engine, that'll let you know. if the engine's not built yet it's easy to go with a milder cam now rather than have to re plan your brakes later. i mean, even a mild 318 in a cortina will be very quick no doubt so i wouldn't be going mad on the cam anyway. unless it'll be a strip only car.......

I dont reay know yet? As I dont know enough about cams yet
I would like a lumpy tickover, something like these.
don't go too mad on the 'highest performance' cam on the page when looking. you'll only be disappointed with the car on the road as it'll be flat as a turd in the normal everyday rev range and run out of cylinder head/valve spring/breathing etc at much above 5500-6000 rpm's.
they're designed so you don't need a really lairy cam to get a rowdy idle, best of both sort of deal if you like.

so something like a comp cams thumper or a lunati voodoo then. drive nice (brakes inc') but rowdy idle.

I've got the Lunati Voodoo in my 340 stroker and very pleased - has enough lumpy idle so you know its got a cam and had no problem with Vac for the brakes I think it was the 723 but if your interested I will check the numbers !
