i read about this guy in FocusFanatic magazine having his done by Cosworth.. "READ" that his all motor set-up was 200hp. i dont think anyone on here has done that though. .. oh if you have that Mag, its like a stock look red svt with i think im eye lids on his headlights...and a black stripe down the sides of the car.. ill have to find the mag. good luck though

I have read a few to many stories about slef porting jobs going to hell to chance it. Have fun if you do and honestly good luck. I thought the SVT flowed pretty much at the max it could

If it tastes good to you, you can pay up something like $3000 (after the conversion from GBP - british pounds) plus a ~800GBP core charge, to get a P&P ST170 head and cams that dynos at something north of 200whp. I contacted them a while ago about the cams (cncheads.co.uk if you wanna look) and found their customer service wanting.
Other than that, didnt I hear CFM was going to offer a better head for the SVT?
On second thought, I think B16SIR did a PNP, last I heard he was on some NA power quest.

I have done mine and do this regularly. if youre interested, i can do it for you. Im currently doing "blanezx3"'s for him right now. I can post some pics later if you want any.

The head is very good stock, it actually has bigger valves than even the FRPP ones that are an upgrade for the standard zetec head. But, theres always room for improvement. Pm me if youre interested in having me do it. Of course i cant CNC the head, but i have been porting and polishing for more than 20 years.

I port matched my head with a 1/4 inch die grinder and gaskets to match against. noticeable change in performance. dyno showed about 10 tq to the wheels between 2500 and 5000, but little change in peak numbers
