Continuing from your other thread I see...
What kind of budget are you working with? What kind of HP/ETs are you looking for? Something like the AI 200cc stock ported heads on a good bottom end can with good tuning and the proper bolt-ons can provide the results like in my signature.
And regardless of what heads you use the 503 isn't an optimal cam for a 383.

The only heads you will be able to buy for 1500 probably some Edlebrocks or even stock castings haha.
They are on the small side for a 383 anyways.
You need to spend monies to make powars!!!!!!!!!!!!!!

Are you on the stock 10 bolt and stock rear suspension? If your on a really tight budget your best bet is to TAKE YOUR TIME and pick up a set of used ported stockers in the classifieds on here, every now and then a set of LE2s or something will come up.

I dont know what it costs to port a set of stock head but if it is 1500 to do it. I would get a set of AFR's for 2k or with valves and and completed for 2500. Then you have a 3/4 deck to do anything you want down the road. Plus you get 2.02 or 2.08 intake valves depending on head size. Just get the size of runners for you application. Get to big of head (runners) and street driveablity will go down and power will not be right. If doing 400 or so hp I would think 190's or 195's would be good. But best to call them and see what they would recommend.
I did the AFR castings with TPIS porting. Those flow between the AFR 195's and the 210's if I remember correctly. NA I am at about 450 but I built the motor to be blown so I figured to keep street performance and decent milage talking 25 mpg out on interstate. But yet big enough to put boost to it and make some big numbers.

Ported stock heads have been well into the 9s NA, nitrous and boost, including a twin turbo car putting over 1000rwhp down. The guy claiming you need aftermarket heads surely means his setup made 450flywheel HP. If you look at Ramair95TA's setup that is 455 at the tire through an automatic and 9" so it is likely up closer to 550 at the flywheel. Not to mention the ported trickflow 21degree from that same company has recently done 490rwhp with a hydraulic cam.

Could have those heads for the same $2500.
Have to watch out for the bench racers and look for actual results.
The guy I bought my first set of core LT1 heads from was selling them so he could buy TPIS ported AFRs, end of that winter I had a junkyard shortblock Caprice with ported GM heads and he had a stroker camaro with ported AFR heads and my pig was as fast on street tires as his was on ET Streets. When I sold those heads he seriously considered buying them back so he could put a good performing head on rather than the TPIS ported AFR. The cash just wasn't there at the time.

that was not at the flywheel for the 450......that was done in the car on a chassis dyno.
And I dont doubt that lt1 stock castings are in the 9's, but then my question is how relieable are they?
These aftermarket heads have a 3/4 inch deck for a reason. How many runs do they do before they
have to change head gaskets because they have blown out? Are they just track cars? How many
street driven miles on them? From what I have read and have experienced unless they like dropping
there motors out of these f-bodys or vette...or anything else that is a tight fit....its better to be safe
than sorry.

A set of stockers ported by the right folks are more than adequate for most applications. And don't base a whole lot of your decisions on a dyno number. Find someone whose accomplishing what you want to do and pick their brain. My old car still runs a set of LPE/Eric Bradby ported stockers with 2.00/1.56 valves, a weenie 226/234 .568" cam, and is still running 11.20s at 122ish...going on its 17th year...and my old car only makes 375rwhp on a calibrated mustang dyno.
