What motor and have they been milled?
My 4.8 came stock with 706s you shouldn't have any ptv issues unless they've been milled way down.
Well they have the bigger valves in them now but that's what my 5.3 has on it now 862 witch are the same I picked them cause I didn't want to change the compression
im running a tr 220 cam, .551 lift, with p&p 706 heads milled .012 no issues running 7.4 rods?
Im running trickflow 205s pnp with a custom cam .588/.589 lift no issues here
