The problem is when I do it, if it breaks it is not OPM, it is my money.
Why do it half assed?
PS, cool that you got a porsche crank, now you know you have what is a known good starting point.

OPM is the best kind.
Lots of probabilities that we just don't have the sample size to quantify:
Failure rate of the welded crank
Failure rate of a new Porsche crank(yes, they have)
Failure rate of the Farndon crank(? a non-zero number)
We are supposing that the first has the highest failure rate. But how much higher? And at what cost do we avoid that 'potential' differential failure probability? If it were an aircraft where peoples lives are at stake, no question - new crank with full inspection. It's not aircraft, it's a car. Worst case, the block is destroyed and he sources another block and goes back again. Even with that, the price of going with the welded crank is still lower than the price of the new Porsche or new Farndon crank.
So, the cure is worse than the disease in this case. Go with welded, if it breaks, oh well.

Think about it - "Umm, hello, is this Porsche? Yeah, I got this crank from you with a 24mth warranty... You see, I was bouncing off the limiter on the main straight of the Nurburgring in 5th at 175mph trying to hold off the 944 Turbo and there was not enough oil in the dry sump tank and... Listen, I will be ok since you warrantied the crank? Yes? Hello, hello, hello, anybody there?"
