Re: Whats the MAX you can port Victor Jr Heads??
Your not going to find an absolute flow limit for your head. Too many variables with different porters and different flow benches. Best you can do is search the internet articles and if it sounds too far fetched, it probably is. Check Fox Lake Racing or Bennet as they are both known good porters of your heads. I'd take a wild guess and say that the 320-330 (post corrected) range would be pretty much it IF larger valves are also installed to take advantage of the flow. That could put a 3000lb car into the high 9's or low 10's.
If you really, really want to go this route, contact MCRP (Mike Curio) in PA or Duane Bush in NC and you'll have one of the baddest set of heads out there. I'd say that you'll also have well over $1500 more in them, plus the matched ported Super Victor intake will also set you back close to $750 just in labor. Small tube headers will then become a concern and you'll need to step up to 1 7/8 or 2" primary tube headers to take advantage of all that work.
Without some type of power adder, you're not going to reach 600 wheel HP with the Vic Jr, even if max ported. Your going to need to look either at the 240+ cc high ports, ported Victors, or build a Clevor with a decent aftermarket head.
I would also suggest getting your suspension and drivetrain in order now before adding that much HP. That is every bit as critical, if not more, than engine HP. You should be able to run an 11.50 with the power you already have. Also do what you can to lighten the car up as much as possible and strengthen the weak points.
