Throw in a dial gauge to determine #1 TDC instead of relying on the case parting line and you're even better.
Neil's experiences are bleeding edge race cars where they were trying to squeeze out every bit.
The average shade tree mechanic at home probably ought to just follow the manual.....

Let me tell you, Its a pain in the ass being Neil Harvey!!!
Point taken, but engines do run better when all cylinders have the same valve timing. Yes, Porsche gives a spec, but that works only if the cams are ground correctly and the rocker arms are refaced correctly. The way I suggested allows you to check.
Also, I do read these forums and often I read about unfortunate circumstances where a DIY made a mistake and the engine fails after rebuilding, or similar. The forum readers all give their sympathy and give the owner a thumbs up it will all be Ok.
Then you read about a shop having the same misfortune and the wrath of this forums lets loose on the shop. Double standard, maybe whichever position you are standing I guess. To eliminate this from happening we have chosen to build at a level where we make sure we cover all areas.
But we are human too and we do make mistakes. Its a matter of catching them before the engine leaves here. My past work history taught me one way only and one right only. Curse, maybe but it is humbling when the opportunities I had most will never have.
