looking for 1 exhaust valve

[sam]

hi, my 80 quattro has a 10v turbo motor in it on 034efi management and it has never ran right, so i decided to go back to basics rather than blaming myself for been useless at mapping lol(i still think that but...) anyway i did a quick compression test using the end of a ratchet in the plug holes lol number 1 had nothing number 2 was good and the rest were ok, so i pulled the head off to find out the valves werent seating right on no1 so i took them all out and started to grind them back in, only to find 1 of the exhaust valves was ovaled and cracked not to worry i'll go get my spare 10v head, 20 minute drive each way had the spare head on the bench, out came an exhaust valve.. and guess what, its different lol 2mm smaller across the face slightly shorter and only 1 groove for the collet............phoned audi, and gave part number"its not an audi part" so gave them the inlet valve part number and he says NLA so does any1 know were i'll find a valve that is
98.43mm overall length
7.92mm shaft
34.8mm across the face
on the valve is written SV035/3T-T33145 so i rang Specialist Valves and they dont list it or have anything similar and for a few new 1s made would be 2k lol due to it having to go through 22machines from start to finish.
searching on google i found this,
EXHAUST VALVE EUROSPEC

35mm x 8mm x 98.5mm
$ 12.00

035 109 611 F/35

anyone know what this valve is for? i need it quickly otherwise i'd buy 1 from the site them specs above are from. please help and sorry about the essay lol

sounds like you have a head with larger exhaust and inlet valves maybe. what size are the inlet valves? Is it ported and polished too?

You could try contacting tho's company's who make big valve heads. ?

but then again, you are talking about a 10v turbo head. so i don't know if the valve sizes are suppose to be the same as a kv or not.

someone else on here should know better than me, but all i know is that the valves in my engine have been increased from 38mm to 41 on the inlet, and 33mm to 35mm on the exhaust!

Big valve head tuners were ppl like: TSR, GTI ENGINEERING, etc etc. there are others.

hope this helps.

woops forgot to update the post.....
after trying alot of places i ended up in andrew page (car parts supplier) and read through the valve book lol and eventually i found a volvo 244 turbo that was exact in dimensions apart from the length(too long) so gave it to my mate who proceeded to cut the end of and machine the grooves in for the colletts

the head is back on now so unfortunately i cant measure the inlets lol
