Having thought further on the subject could I just remove the wavy washers and shim to suit clearance and rocker position?
It sounds like you have hydraulic rocker gear (solid spacers and wavy washers, not springs), so yes you could shim the solid spacers (0.004” total side clearance, any more and they’ll rattle). Set the rockers axial position first, then geometry. I’ve used 10mm TP swivel foot adjusters and 2.0l rockers, shims under the rocker pedestals and CSP HD aluminium pushrods cut to length. http://www.tp-technologie.de/produkte ventileinstellsch en.htm https://www.csp-shop.com/en/engine/push-rods-aluminium-109-301-2950a-10984a.html If you use standard adjusters, you probably won’t need pedestal shims, use swivel foot adjusters and you probably will, if you do need shims, they must be the same thickness. If you have 1700 rockers you could use Porsche adjusters but they won’t fit in 1800/2.0l rockers. If you use TP adjusters the rocker will need to be modified (countersunk to allow the foot to swivel). The VW steel pushrods for hydraulic lifters are 10mm longer than solid and can’t be used with a C35 (or any other solid cam). If you want Chrome-Moly rods they’ll have to be cut to length, or bought at the correct length once you’ve worked out the geometry.
I made my own solid spacers using bronze bushes and shims... I used the same TP feet ss 77Westy.. mods required as above comments but it's in the thread i posted a bit of earlier..6 years in the tintop and still going fine barely need any adjusting so far... even if she is playing up this week!

77Westy Deefer66, Thank you for your detailed responses. Did either of you have to do any mods to the rocker arms to allow full articulation of the Elephnants foot? did they have a lubricating hole down the middle? is it needed? Ive thought about these from Heritage, they are cheaper and no postage. https://www.heritagepartscentre.com...BwM1t6aeHzvVcWNF2SpDOQycuM83-Y-QaAnPeEALw_wcB However it states "NOTE: Not recommended for use with K-800 or VW650 valve springs." I have no idea which springs they are. I have single HD springs supplied with the C35 cam would they be suitable with these push rods? 77Westy The CSP rods only carry a restriction of operating with a single HD spring, are they the same rods from same manufacture do you think? When setting up and shimming the rocker shaft, I assume the elephants foot will be inline looking from both directions? or do you still allow for a slight off set to rotate the valve? or does a flat foot allow for ANY rotation? So to summarise its, Elephants feet. Solid spacers and shimmed up wihtout wavey washers Adjustable push rods. Thanks again for your patience and valuable input.
Mods I made as in the links below( hopefully they work I cut and pasted them from the front sheet of the resto thread!), no holes as far as I know in the feet/stems but don't seem to have a problem so far all rock slightly when checking gaps, which takes a bit of getting used to but when the gap is right they don't rock at all so feeler guage slides better if you see what I mean? I used stock rods and shimmed up the rockers without too much problem to get mid stem at mid-lift one way and shims on the shaft to hold the rockers at the mid stem with a bit of tolerance/play. I used scat HD springs as recommended by aircooled.net when I got the new cam. Rotation was something I looked at but not sure if most of the rotation comes from the spring uncoiling than an offset rocker. A flat foot isn't going to really apply offset load to spin anyway, and if Porche like them why not?

They must have improved those is all I can say. The set that came with my Type-1 C35 were a joke, all different heights and wonky as a banana. I ended up using the set that came with 40mm AA heads which were blurry lovely!
Thank you for taking the time to send the attachements, very interesting. You cant beat photos, so so much better than reading and typing.
The pushrods might be from the same manufacturer; the spec and price in Europe is virtually identical. Note they are intended for type1 engines so are really too long for a type4 and shortening them more than 12.7mm in not as simple as chopping a bit more off (the tube bore is counterbored at the end for the tip). Rocker spacers I made from steel tube, cut to length. And I offset the adjuster slightly to encourage the valve to rotate. I simply countersunk the rocker to allow articulation of the swivel foot – I don’t see any point in thinning the rocker, they don’t touch the spring retainers with standard adjusting screws so why would they with swivel foot adjusters?
Probably right on that.. without shims. I found at full lift the full range of articulation wasn't possible but with them and geometey sorted it would prob be ok with a bit of countersinking
No such thing as a stupid question, although there might be stupid answers. The CSP aluminium pushrods are supposed to be suitable for type 1 and type 4 engines, and they are as long as you are aware that the bore needs to be counterbored deeper for a type 4. If the rod is simply cut to length the tip can’t be pushed fully in the end. The CB rods are almost certainly the same. Steel rods are available for the type 4 but I’ve never used them.
So I have been reading up on stuff....again. I have in my possession the following: Steel pushrods 260mm, must have been for the GE hydraulic tappet 10mm Dia. Aluminium pushrods 270mm 12mm Dia, standard 2.0 engine Samba guys are on to Stateside Tuning and he gets good reviews for swivel feet on the following, https://www.statesidetuning.co.uk/newproducts.html Has anybody used these, Im temptedto try them. He also has cut-to-length Pushrods 285.75mm. (shorter than CSP 's 292mm). Roughly how much would I be needing to cut off for a C35 cam? he states both Pushrods and Feet can be used on type 1 and type 4. I tried http://www.tp-technologie.de/produkte ventileinstellsch en.htm but couldnt find how or where to order them from, I emailed them in German and English but no response. It might be me being a bit thick......... Am I correct in saying the standard rocker arm ratio type4 2.0 is 1.3?
Those Stareside ones look like he bougth them from TP.. but at least it looks looks he's updated his website for the first time in a while.. Thorsten has always been very helpful by email for me info@tp-technologie.de. even returning cash when i paid twice ordering online. 1.3 to one sounda familiar to me.

I used the contact button on his website.. i fixed the email on my last post. Then bank transfer once confirmed details. Had no bother twice now. It was 72 euros incl postage 3 years ago. Webcam as in pic in the dokka . Stock pushrods . Sent from my SM-T580 using Tapatalk
Stateside Tuning sells TP swivel foot adjusters, the same parts, just more expensive than buying direct from Thorsten. You’ll need to cut 10mm - 15mm off the rods, but that’s very approximate, every engine is different and you have machined lots of the parts. Standard type 4 rocker ratio is approximately 1.3:1
Just got a mail return from Stateside, price on web sits for swivel feet, any size is £65 plus vat and P&P, now its gone up to £90 plus vat and P&P
About £51 incl. VAT direct from tp-technologie.de It’s easy to pay Thorsten by bank transfer, he’s very helpful and I’ve never had a problem. He usually uses DHL for delivery, just contact him for the total price. info@tp-technologie.de
