Didn’t finish the valve job so no flow numbers today but the porting and double cut clean up is done on the first head. I needed parts bad so I looked up the part numbers for valve seals (6 sets) 2.055 valves (3 sets) 2.08 valves (2sets) 1.60 valves (2 sets) LS 2.02 valves (2 sets). 1000.00 at least later my order is in.
