Affordable heads for 408

Affordable heads for 408
I don't have a lot of money right now, but these stock 317 heads are choking the setup to no avail. I've only got LS6/ported TB at the moment so no 90/90 yet. I want to get the heads dealt with first, then the intake setup can be swapped easy. So what are some budget heads available that work well with a 408 N/A setup built for around 11.2:1 SCR (with 72cc heads)? I want to keep my SCR up in that range as I won't be going power adder. My setup is listed below:
HPE 408
11.2:1 SCR
244/248 635/627 112
Eagle crank
Callies rods
Diamond flat top pistons w/ 2cc reliefs
Stock 6.0 heads
SVO 42 #'s
LS6 intake
P/P stock TB
Edelbrock 1 7/8 stepped LT's/ORY
LM catback
I made 425/445 with this setup but am looking to get more towards 500 with some *cheaper* heads and a 90/90 eventually.

Negative, haven't been hearing much about budget heads for 408's since most threads are about the ETP's or another set of badass heads that I can't afford. I'm looking for some heads in the range of $1000-$1300 most likely. I'm just trying to get some decent improvement over the stock 317's without breaking the bank for the upcoming 90/90.

Problem is, affordable and power don't exactly fit in the same sentence.
Everyone always says this, so i'm sure you've heard it before.... Don't skimp on heads. It's the one part that is the base of all your power to come
HEar it all the time "all your power comes from the heads" save up for another month or two til you can afford some AFR or comparable heads!

i'm going the 402 route and i guess i will just have to splurge and get the ets or afrs probably. i think sdpc has a budget type head that put up 619 fwhp with the sdpc shortblock, 90/90 and 242/242 cam. the ported darts or prcs may be close as well.

I'll check into Summit's pricing for the Dart's and see what comes along with them.
