Well I've had a chat with Newman Cams and explained the situation. I'm sending my cam off this weekend and they are going to "have a look and see what they can do!". As soon as i get it back I'll post some pics. Unfortunately I will have to send the rockers separately as I've just blown a chunk of my cash on a pair of Mikuni VM30s from Allens Performance Parts which arrived today (only ordered them Tuesday so well impressed with the turnaround)! Hopefully Newman cams will be able to put a stellite pad on the rockers unless I can source some old syle used ones in good condition in the interim. AshimotoK0, do you know if the lift on the fatcam is the same as the later cams?

Thanks for taking the time to take those picks AshimotoK0! I think i am now confident that I have the correct rockers, even though mine are badly worn and the numbering on the casts doesn't appear to be consistent. Your cam lobe faces are in much better condition than mine! Do you know if the dimensions for the early asymmetric camshaft are available anywhere? I've had a trawl through google but have come up empty handed! I will call Newman camshafts tomorrow to see if they require them in order to sort the camshaft! Cheers again for all the assistance!

Evening folks, once again many thanks for the wisdom! This is my first project like this and I'm loving every minute, despite the never ending challenges! This site is an amazing resource and I am most grateful for all the help, the information has been really useful! The head is pretty coked up but no obvious damage although I will give it a clean tomorrow and inspect thoroughly. While the pistons are pretty crappy there is no catastrophic damage with rings and lands intact. Newman cams quoted £60+vat for camshaft re-grind and £37.50+vat for stellite pads on each rocker but this was sight unseen and he asked me to send them in for an initial inspection so price is obviously subject to change. I notice on CMSNL that the rockers for the USA K0 CL350 have no numbers visible on the casting but do have a right angled "hump" on the spine of the cam follower end, the same as my pics, whereas the 312 rockers have a smoother curve on the spine of the cam follower end. Do people think I'm safe making the leap that I have the correct rockers for the early camshaft?

Cheers for the info K2-K6! I have posted pics of the pistons below! Going back to the cam and rockers issue, I have also posted pics of the wear on the cam followers and any identifying numbers on the rocker castings. The mystery deepens as there are three different numbers: 11, 26, 8 (or 6) & 11 (although they all seem identical in appearance to me?). The two rockers on the left were located on the left & right inlet cam lobes while the two on the right were located on the left and right exhaust cam lobes. Does anyone know if the numbering is significant? Should I be worried? For the pistons, the badly pitted one was located in the left cylinder. There does appear to be some scuffing on the edge of the piston crown. As i said previously, because the pistons are standard I will be re-boring. Not sure whether to just go up one size or bite the bullet and go big bore kit! Anyone have any experience either way? I will be getting Mikuni VM30s carbs as the Keihins were buggered! I've been quoted £330 jetted for standard.

Thanks for all the info Bryanj/AshimotoK0. I noticed that the rockers on CMS had the number 312 on the casting for early models but wasn't sure if this was just due to a "stock" photo being used? Just had a chat with Newman Cams and they will have a look at my parts. He said they would normally put a stellite pad on the rocker and re-grind the lobes if they weren't too baddly worn/pitted! He di say they have some k4 blanks so am wondering if anything could be done with one of those? Looks like I'm caught between a rocker and a hardface (sorry!).

Many thanks for clearing that up AshimotoK0. The rockers were heavily worn and I now wonder if the previous owner has used the wrong type? Will check this evening! Do you know if these cams can be hardfaced and re-ground? Can anyone reccomend an engineering firm/cam specialist? Cheers!

Hi folks, recently acquired a (non running)1969 CL350 and finally got around to tearing down the top end. Pistons, head and valves heavily crusted in thick carbon deposits and strange pitting on piston crowns. Barrels seem in reasonable shape (although no "crosshatching" visible but was going to re-bore anyway) and compression seemed ok (by feel, not measured). Pistons were measured and are standard but the cam lobes seem like they have been reground asymmetricaly for faster valve closure (I think) - see pics. I assume this was intentional and not due to wear as all the cam lobes appear to be the same shape with some pitting at the apex. If this was a performance mod it seems odd due to standard pistons. Maybe heavy carbonisation due to failure to re-jet after cam mod? I'm just scratching around in the dark here! Anyone seen anything similar before?
