Bryanj, thats good to know thats normal looking, I've never had to do this before to know the difference.
Chris, I have that part book in PDF so I may as well print it for now and save some pennies for engine parts! Its a good manual though and has helped me identify some of the parts I'm missing so far.
I just had a closer look at the cam and the cylinder head and the cam tolerances are just within the wear limits according to the clymer manual, but I might just replace it to be sure.

It also looks like a new head might be in order as the cam bearings are very deeply scored as you can see in this picture.

If I went down the acquiring a used head, would I have to get it skimmed to match the block face?

Take your point entirely, your rebuild is going to be an expensive business!
If you get some of those plastic ring-binder wallets and put the pages in you won't even get the pages oily.
With cost saving in mind I was curious and had a look to see how the exhaust prices compare.
Saisei headers and collector only are £327.60. Motad starting price is £129.99 (both + carriage).
You pays your money and you takes your choice, and to some extent maybe get what you pay for, but that's a lot of pennies difference.

Wow that's a massive difference in price! And a 10 year guarantee. Where did you see that deal Chris? Motad's website shows no price and possibly out of stock.

Motad is a member here and very friendly. Look up motad uk in the members list and pm Ian. They may be making more of the stainless ones if that's taking your fancy.
Broken rings: interesting what Bryan says. Member ManicGTI has the same problem and posted pics. Check his thread. Most likely the broken bits stayed in the groove.
Yes I thought your cam journals looked suspect in the pics :( oh well.
These days it seems hex bolts are out of fashion. Back in the day it was the thing to do! Now originality is prized and anyway hex bolts (I mean allen bolts) retain water :o
Keep it coming
tom400f:
Do the pistons have any oversize markings? Would expect them to be on the crown but may be the recessed part of the skirt.
Crankcase bolts... Haynes chapter 1 section 44 for all your bolt order and position needs! If I could do it as a naive 19 y/o then it can't be that hard :P
