Default I need help picking some heads...

I know people are going to hate me for making a thread like this but i just cant make up my mind. I dont want to spend 2k for heads just like 1-1500. I was looking at TSP and some of their heads:

PRC ls6 heads
PRC ls6 stage 2.5
One of their 5.3 heads

Any other suggestions?

I was also thinking of getting a little bigger cam to go with my heads. I ahve a 224 now. My shift points are 6k and i do not want to go any higher than that since i still have stock tranny. So if you have any suggestion on a h/c setup please let me know. I would like to see over 400. I have all bolt ons with 3600 stall and 3.73 gears. I never dynoed it but i figure i have around 380 now, i raced a cobra with 420-430 and stayed exactly side by side.
Thank you.

you are probably alittle shy of 380 right now because of the auto but if you go to a bigger cam you will need to raise your shift points also or you would be defeating the purpose of a bigger cam.i'd go with a set of heads that has a small runner like an afr 205 which has high velocity to keep all that midrange power.i don't think you will improve performance much with a set of ported heads and bigger cam unless you raise your shift points to atleast 6300-6500.
