RR200 port work

[Nick]

Im thinking about some port work in quest for some more power. Heres a quick loook at my motor
-11.1:1 350
-Brodix RR200 heads 2.055/1.6 valves w 60cc CNC chambers
-Weiand Team G
-750 mighty demon
-296/302, 258/264@.050 .562/.562 lift on a 108 solid FT cam
-1.5/1.5 roller rockers
-1 7/8"x 3.5" headers

The motor has propelled a 3500 lb car 116MPH in the 1/4. What kind of power increase would i expect from a full port job from CFM. Also what would i be paying for this? Would i be best off to get an intake {victor jr?} done to match this as well or would that be a waste of money? Let me know thanks..

Full port would put you about 119 to 121 mph. Should give you 40 to 60 HP or so. The porting would cost you $750 and it would run another $200 to freshen the heads.

Mike, a few more questions...
1. What does the $200 dollar freshening entail?
2. Does the $750 include the intake or is that extra? Is it even needed?
3. What would the final CC of the intake runners be roughly? 4.Would the port job hurt my low lift flow?
5.Will it hurt low end performance?
6. Lastly, if I upgrade to 383 inches will these heads be ideal?
7. What would the turn around on them be?
Sorry i know its alot of questions. Thanks in advance for your answers.

$200 goes towards a valve job, cleaning, light milling, etc to make sure the heads are fresh.

$750 is just for the heads. the intake would run about $50 to 100 more.

Final cc of the runners would end up around 218 to 220 for the appropriate volume and flow.

The low lift numbers would come up proportionately with the other numbers.

Torque will increase with the added flow even with a larger port volume.

The heads will work great on a 383 as well.

Turn around would be about 2 weeks.
