The stock "rod bolts" are known to be a weak point on the 3.2 /3.3 motors because of there reduced size compared to the SC and earlier bolts.
I think Porsche used stock bolts on the Club Sport and took the RPM limit to something like 6850.
7000rpm should be more than fine I would hope w race bolts. With lighter pistons like J&E's one should think 7k would be well within reasonable limits for even race duty but I do not know that for sure (I would do it.).
There just has not been that many reported stock rod bolt failures it seems. I think I have only seen one reported in all the posts I have seen here and I think that motor saw a lot of race duty.
Valve float should of course be addressed (springs and/or lighter retainers - talk to the cam supplier) and at some point crank oiling (pressure limit and or cross drilling) depending on how far up the RPM range we reach -- but those are separate points.
To me the question still remains: with race bolts what is a reasonable limit w stock pistons and or with light weight race pistons.
