SVT has engine vin 5 Bent valves need Help

Ok guys here the deal I had a timing belt idler pull bolt break on my 2002 SVT
all the exhaust valves are bent and maybe one or 2 intake valves

When I removed the head and took it to the machine shop he said the valves had three groooves at the retainer location and the SVT valves have only one or two grooves.

When I looked up engine vin 5 of my vin number it said it was a ZX3 code
and valves for this one on Rockauto.com shows 3 groove retainer on valves made for the ZX3.

So do I have a SVT engine or a ZX3?
because they where different part numbers for both and different valves lengths size ect.

also do any of you have Ford shop manual for the 2002-2003?
There was some mention of needing to make a alignment pin with groove cut in the end to use to align the head and gasket to block deck up on reinstalling the head need to know what the size of that tooling is?
Or could I cut head of old head bolts and use them as the alignment tool?

Thanks in advance for any help
Barry

I just tore down the head from my SVT and the valves have 3 grooves at the retainer.
I think your machinist is misinformed.
Can he not see the difference looking down the port to recognize an SVT head?

Thanks Guys,
It was sold to me as a SVT car from the dealship used
Just was question it as this is the first time I have ran into problem with getting correct parts for it normaly buy SVT parts and they have fit
So the SVT valve has three groove retainer also for the SVT version head as well as some of the other heads such as just differentes, length and head diameter?
Is the 3 groove retainer just on the SVT valve or others as well?

I was planning on using head studs when I put it back together so I hadn't given it much thought.

Yes I thought about using the ARP Studs as some say it is easier to get a even torque on the head an easier to get alignment
Its just that I had already bought the torx head bolts from ford.
Have you heard of any pros and cons of using ether or just your preference?

I'd use what you got. Torx= meaning torque to yield bolts?

ARP / studs hold better but need to be torqued down 6-8 times to get them tight , the stock bolts are stretch to yield which I dont like much

Pictures of your engine / head will say in seconds what head you have

Depending on what software the machine shop is using, they may have to look for a later year SVT or ST170.

The SVT, engine VIN 5, does have a 3 groove valve keeper and valve stem.
The valves are specific only to the SVT/ST170.
You can not drop in any zetec, engine VIN 3, valvetrain parts.

I've not seen any other source for parts besides Ford. Which is to say, no parts store can get them.
