Re: Which Head and Cam?
Anyone of these packages will get your desired hp:

Below is a basic run down on the head and cam packages. The best package will depend on HP goals, budget, rear gears, stall size, future plans, emissions, driving style, tuning ability, existing components, etc., etc, A phone call would be best to make sure that we can talk through these things and get a package that will work like you are wanting it to and also make sure that you have the complimenting parts to make each set up work.
I offer cam and head packager from $1100 to $1650.
-----------------------------------------------------------------------------------------------------
LE1 cam pulls from 2000 to 6200 RPM and should make 370-390 RWHP with matching heads, 30 lb injectors, 52 TB, 1 3/4 LTs, No cats, good tuning, etc. The heads are ported using stock valves, performance valve job, back cut valves, CM 612 springs, retainers and locks, milling, cleaning and assembly. These heads flow about 255/180 with a 195 cc intake port and stock LT1's flow about 215/150 with a 170 cc intake port.
Heads and cam are $1100 (plus shipping). This has the RPM range of the Hot Cam, CC 305, etc. but makes more HP and TQ over these cams through out the entire RPM range. This will work with any gear and converter but the track times will be better with a stall and some gear.
-------------------------------------------------------------------------------------------------------
LE2 cam pulls from 2200 to 6500 RPM and should make 400-420 RWHP with matching heads, 30-36 lb injectors, 52-58 mm TB, 1 3/4 LT's, no cats, GOOD tuning, etc. The heads are ported and machined for larger Ferrea 2.00/1.56 valves, matching springs (Comp 987/977 springs and Ti retainers or Bee Hive springs and CM retainers depending on lifter type and EXACT cam specs), locks, locators, milling, cleaning and assembly. These will flow about 270/190 with a 205 cc intake port.
Heads and cam are $1650 (plus shipping) and will need GOOD tuning. This has the RPM range of the CC 306 cam but will make more HP and TQ at peak and across the board. The REAL difference will be the LE2 cam will make TQ in the 2500 RPM range and the cc 306 doesn't start until way past this.
-----------------------------------------------------------------------------------------------------
LE3 cam pulls from 2600 to 6800 RPM in a 350 (2300 to 6500 RPM in a 383) and should make 410 to 430 RWHP with matching heads, 36-42 lb injectors, 58 TB or mono blade, GOOD tuning, etc, etc, etc. These are the same heads as above. This type of RPM requires a lot more spring pressure and will also need Comp R lifters to handle the spring pressure.
Heads and cam are $1650 (plus shipping) and will need GOOD tuning. This cam is similar to the GM 847 cam but makes about 10 more HP at peak and starts making HP sooner. Makes more HP and TQ across the board. Needs gear and converter to work well in a 350. Pretty much a racing cam for the 350 or a good street cam that will act like the LE2 in a 383.
-----------------------------------------------------------------------------------------------------
Everyone has a different opinion about what is streetable and what a safe RPM limit is for their engine.
If you are looking for just cylinder heads and with out a cam, the heads are priced at . . . . .
$750 for the LE1 heads only
$1300 for the LE2 heads only
$1300 for the LE3 heads only
Give me a call and I can help you pick a combo that you will be happy with.

Re: Which Head and Cam?
I would go with AI. You pay a little more but you get what you pay for. i don't think Lloyd has anyone putting out 440+ rwhp on ported stock casting on a 350.

Phil & Ron at AI and Lloyd at EPW both offer ways to help you reach your goals. Call them both and run with who you like and meets your budget. I went with AI and the product and customer service for me were awesome. I highly recommend AI too.
