Thinking of pulling the trigger on the AI 190 with the 226/234 I have the 503 now. Car also has headers,3:73 gears,Edge 3400 stall,comp 1.6....... the usual. I it rebuild it around 1000 miles ago went back all stock except cam and ARP rod bolts.
It is a street only car I might take it to the strip once or twice to see what it will do nothing more.
Would it be any benefit to spend the money on the heads if it's only a street car? I have also thought about putting the 226/234 and calling done. Any Thoughts?

Those heads will make a huge difference over stock heads. They'll roughly double the power increase you'll get from the cam alone.
Do it!

I had the AI 190s and 226/234 cam and really liked he combo with 3400 stall and 3.73s.

I am sure it would gain you power over the 503 but if it would gain enough to be worth the time and money is a question for you

I put down 373rwhp with milled stock heads. I know heads make a big difference, but you get your bang for the buck cam only too.

Would the stock injectors be fine at the power level with the AI 190s and 226/234 or 503 cam? I've been thinking of getting those heads also.

Based on the fact that SVO 30's support 500 rwhp through an A4, I'd say the stock 24's will be plenty for the 503 cam and those heads. The 226/234 cam will get close to the limit, but I would try it if it were mine. For a street/strip car, don't worry about duty cycle shown by datalogging at WOT; if the A/F is good per the wideband, you're good. Only if you're roadracing the car on a big track or doing topend runs would I worry about DC.

This might be the way I go for awhile,then maybe next winter do the heads. But who knows depends on how I fill when I tear into it.
That's impressive with just a cam and not much head work done.

I have the 190s on my 355 right now. When I had it in the car I loved them. Even seems im running the old GM847 cam. Huge difference over stock. Best bang for the buck!!

yep Im very happy with it. To clarify that was with an AI 226/234 and I had the valve bowls polished up a bit but NO runner porting.

Would there be any reason not to just spend the extra few bucks for the AI 200s?
