Silber, I am not a professional engine builder by any means.. but to build a performance engine that will last a long time, I would suggest sending the parts that you want to measure to a professional engine builder (or a specialized engine machine shop) that use precision measuring tools that will give you 100% accurate readings, I strongly believe that the cost would be cheap compared with a no so good build due to questionable measurements.
Please don't take me wrong I have used plastigauge in the past on a few engine builds (air cooled VW's, Alfas, Chevys, etc.,) and I feel that got lucky perhaps because the tolerances on those applications were not as critical) but after attending the Flat6innovations M96/97 engine building class, IMHO would not do it on a Porsche engine with very tight tolerances..
