I'm in the process of rebuilding a Testastretta 998/999 engine. I have all of the engine cases, heads, cylinders, etc. vapour blasted as they were all in a right state. However, the vapour blasting process has taken, what I assumed is/was, anodising off the spark plug tubes in the heads and off the static and tensioner wheels spindles. I know that this won't affect the running of the engine but it's triggering my OCD and I wonder if it's OK to remove them and have them recoated? The belt wheel spindles have flat edges for a spanner and I assume they are tightened in with thread lock. So presumably some heat and a bit of force will take care of them. I feel like the spark plug tubes though might be a different story. Looking on a parts diagram the tube cannot be purchased separately from the head. Again I once the bolts are removed I guess its a bit of heat some force. So my question is, has anyone had experience removing and refitting these parts. If so are there any gotchas? Thanks.
