heads! looking for a head the will work great with a streetable cam and give me power throughout the entire rpm and afforability. what size runners and size valves are best suitted for a street application? there's so many to choose from that i'm thinking about so here are the one's i'm thinking about.
You have 3 budget heads and a premium head. They are all gonna work great with a streetable cam. If you wanna pop the money, go for the AFR's. As for the other 3, they are all good heads for the price. Call each of them and buy from who you get the best vibe from.
****, I voted for AFR, but if you are on a budget, you may want to ignore that one. If you can afford them, they are worth the money though. If not, the ported Patriot LS6 heads are a good option.
i would (am) go with PRC 2.5 5.3 liter heads. streetable power from smaller combustion chamber and shorter intake runner. call TSP and theyll give you some good info, but i like everything ive ever heard about them

i figure 205cc is ideal for a stock ls1 motor and anything over 220 is over kill. i want something that will give great low end torque and high horse power. of course afr's are a great choice but with a $2300 price and the others from $1100-$1400 for maybe 10hp less it's an easy choice. like them all, leaning towards livernois stg2 and with there smaller runners at 220cc i fell they give me that low end. but i'm still open if you guys got more info and experience. like to hear about prc ls6 heads and what size runners they are.

Our bench is known to be somewhat conservative compared to others and we would rather underrate our heads slighlty than claim they flow better than they really do.

im with Red...i would look into the PRC 2.5s. I have heard good things about them....guess thats the reason why i got a set of them sitting in the shop waiting to be installed.
I was in the same boat not too long ago. I called around to many places and got a lot of good info. I searched many threads on this site and a few others. I finally spoke to Richard at west coast racing heads. He si a sponsor on here and decided to use him because He actually took time in the middle of the day on out 1st coversation and went through my set up. i was on a budget so he convinced me to port my stock 98 heads (806 castings). He did a great job and flowed better than the afr 205's as promised. These heads are bad *** and look bone stock
. I would give him a call.

Heads Easily for the money. The TSP PRC 2.5 Stage 5.3 Heads were the ones I went with and after 8 months on the car, I still love them. I actually still get a grin when rolling high first gear and lose the tires at the top of the gear also, losing them off the line. Flowed better numbers than a AFR or TrickFlow either for the money. I can always lose 10lbs to make up for the HP!
All of the heads you have listed when matched with a good street cam should do well. I figured I would throw another budget head into the mix.
I Love my TEA 5.3 Stage 1.5 heads. You can compare some of their higher staged head flowrates against some of the others.
My Stage 1.5 heads flowed:
lift....in/exh
.200 137.7 120.9
.300 211.0 183.8
.400 265.1 223.2
.500 300.0 250.1
.600 316.3 260.9
Most of the budget heads should flow well when compared to out of the box AFR, Trickflows, etc. IMO when you start making modifications to them is where they will really start to shine over the budget heads... hence their higher pricing.

I agree with this. I am saving up right now for the heads that I really want cause somewhere down the line I don't want to have to change them. AFR 205's is what i'm getting with a little modification.
