I can not tell, I think Novarossi can not tell either..... from time to time NR is changing specs without telling.

From the 3 JP modded 35+ I have seen they all had the same crank timing. JP has determed his own specs or is changing the original with some left over cranks from his JP engine line. The main differenses I have seen were the exhaust height and from that I can see that through the years they do become higher.

Attached a smal list with timings with some 35+ engines listed
