Head work or Cam change?

okay let me start with I ran my best ET couple weeks ago with my dart. It ran 11.40 @ 116. My 60ft was a 1.58 and my 1/8 mile was 7.21 @ 94mph
Heres my combo:
340
4inch stroke
571/571 248/256 Hyd roller'
RHS heads 2.02/1.625 untouched
11:01 compression
Edelbrock air gap
Pro systems 830 cfm holley
904 Trans w/turbo action 10" stalls around 3800
8 3/4 373 gears
27in tall tire
3350lbs w/driver
My question is I wanna get the car down to 11.00 range and was wondering what my best options would be to change?

More cam, more gear, more converter, more intake

So single plane? and My heads should be fine the way they are? would You go with a solid roller?

I would tune what you have first, jetting, timing, shift points and starting line stall speed, tire pressure and then look at the chassis parts before messing with the motor, make sure it is maxed out all the way from the front bumper bolts to the rear bumper bolts before changing any other parts Concentrate on the 60 ft times first, make that baby moves hard the first 60 ft, as hard as you can get it to The first part I would look at changing once you get it maxed out is the converter, is this a street and strip car or race only?
EDITED: what RPM are you crossing the finish line at now?

Get the heads fully ported fore sure, would be best bang for buck, and should get you 11.00s once tuned. Yes more gear more cam more converter would all help, but head porting is where you will make your biggest gains for the $$$.

Its a street/strip converter. I cross the traps at 6000. I played with the timing and it ran best at 32-34 total. Where would be a good place to have my RHS heads ported at?

Also my fuel system is a holley blue pump with 8an line to the carb. And my suspension is ss 002/003 springs with longer shocks and pinion snubber. And I have 90/10 shocks in the front.

IMO, your current set-up is pretty well matched. It will be a bit of a challange to get what you want from one change. I think you would be best served, like you are planning, to find more power, but understanding that your suspension will become less ideal as the power goes up.

With that said, you're looking for 40 hp or so. I would start with the heads. If you can live with more CR, get that too. This will help you every where in your current power range, and keep you from the "now I need more gear/converter/tire...." syndrome. The next item would be the cam, but again, I would not make a big change there for the same reason. A solid roller or FT with faster ramps similar or slightly larger specs as you have now. Unfortunately, this change would be $$$$.

That's where I would go first also.
