Dont know my flow numbers but here are my specs
505 pump gas motor with 10.75:1 compression.
Custom ground Bullet roller, 640 lift
Hand ported MW Victor heads with 1.6 T&D rockers.
MW Rick Allison cross ram.
835 Holley carbs done by Ken Jones.
2”TTi’s

about the tire smoke on the street, I can cook them at 55mph, 
Eddy makes 2 versions of the victors. got this from the web page
Victor Max Wedge
• Intake ports are machined to match Max Wedge intake manifolds for RB competition big-block Chryslers
• Intake ports are raised .650", exhaust ports are raised .250" for improved flow
• The intake flange is extended .950" to eliminate the need for intake spacer plates
• Exhaust flange is extended .300" from stock (same as Mopar Stage 6) featuring dry exhaust bolt holes with Helicoil® thread inserts
• Sold without springs or retainers; use recommended springs to match your cam
Victor Series Big Block Chrysler
• The best standard port location head available for competition big-block Chryslers
• Intake ports are raised .650", exhaust ports are raised .250" for improved flow
• Will fit Edelbrock Victor manifolds for both high and low deck engines
• Sold without springs or retainers; use recommended springs to match your cam
• Can be machined to match Max Wedge ports
Hope this adds some insight

Yes, you're close. We made 700hp at Comp Cams on 93 octane with 446 inches in 08 using Modern Cylinder Head ported SR's. 370cfm if memory serves correct. It was also 12:1 CR.
 Is that number from CNC porting or hand porting Do any guys besides mine hand port anymore  I just always here about cnc porting now.
Has hand porting become an old school art

I actually have the sr's now, they flow 340 or so.
Like people are pointing out, it depends.
On the flow benches I am familiar with, an SR flowing 340 cfm will be a max wedge port. If not, the number can't be compared to what I know.
A fully ported, max wedge, Victor head can flow ~370 cfm. So if the engine is built right, it could support about 70 more HP. But out of the box, standard port, the Victor will flow less than your heads.
