Can I use 16v connecting rod nuts & bolts to 20v?

I wanna say yes if they are from a 42mm journal size 16v, like a high comp engine or gze crank. It might be the same for the 40mm blue tops. I would check the ARP rod bolt application chart.

they are all the same. it doesnt matter if its 16v or 20v they will work

in my experience with them. the 16v has a 6 point and the 20v has a 12 point. there the same thread size and pitch. all my 20v ones have been 12 point, and when I opened up a largeport 16v a few weeks ago it had regular 6 point nuts
