So, I had to buy a replacement camshaft cap for the tachometer drive (since my broke) for my '79 DOHC CB750, had it checked for clearance and alignment at a reputable machine shop. The technicians have said that the cap will do and now I am in the process of putting together the head on the engine. Also, I got a valve job done too with new seals (valves were rusty and leaky). My question now is:

1. Given the work done, will it require a specific break in procedure? If yes then what would be the right way to do it?

2. I have done my best at cleaning the cylinder block surface using a scrub pad and WD40. The end result is not shiny clean but the surface is smooth and clean enough to not feel any undulations on my fingers. Any thing else I can do? Was that the right way to do it? Plan on doing the same for the head surface.

3. The pistons have carbon on the tops. I plan on reassembling the engine with the carbon as is since I do not have a scraper that's gentle enough for the Aluminum. That ok?

4. Anything else I need to pay attention to? Does then oil pump gasket need sealant?

Thanks in advance!

And here are some pics of the cylinder block surface:

Break in is only for rings to break into the cylinder walls and the cam lobes to match to the tappet shims. One cap won't affect that IF it is right.

Good luck.
