hey guys what’s the optimum or closest to optimum timing for ddp 90's I am in the process of doing a full rebuild so new hg, arp head studs, ported the head, valve job, hd valve springs, 4k gsk, afc spring, possibly putting in ddp delivery valves, and snow water meth we will see how the money flow is so while everything is apart and it’s easy to get to the pump where should I start on timing?

 

I guess the real question is what timing will get the ddp90's spraying right in the bole
