What size cam are you using? Thats a lot of power.

LSWNDR

477/461 same setup as ss2000, Patriot LS6 STG 2.5's milled,
MS4, 36lbz, 255 pump, LS6 intake, Ported T/B, Hooker 1-7/8 LT's, TSP TrueDuals, M6, STG 3 Spec+, Moser 12-bolt, Sticky Mickeys. Not to mention the great tune from the shop. TSP sells the LS6 STG 2.5 H/C package with MS4 for $2150. They know their **** kids lol. If they didn't why would they sell the **** out of them? Why would Guys like myself & others on the boards brag about the bang for the buck and power they produce with right setup. It just goes to show that you don't need aftermarket parts to make good power, no offense to the big sponsors because they rock to. Speed costs boys how fast do you want to go

Why do they sell the **** out of them?Marketing,advertising maybe.If you think one vendor makes a budget head thats significantly better than others you are mistaken.

Because they work, period. They work well enough with their MS4 cam to put a 3700lb NA 346 in the 10s Not all budget heads are created equal - if you think otherwise you are a fool. PRCs biggest competitor sells crap.

Paint it Black - show me a 500rwhp 346 using AFR heads - just one. Cleaned up heads and dyno tricks don't count.

I don't put my trust in dyno numbers. A dyno can read high. BUT.... Patrick's AFR headed 346 put down 508 on a dyno with AFR's, here you go: http://guerragroup.com/PG6-14-07dyno2.jpg

I do care about track times. And the H/C record holder (Juggernaut) went 9.90 with stock bottom end and out of the box AFR's.

And I do like the 243 casting, it has a lot of potential in the right hands. But budget CNC'd heads are not the right hands. The right hands charge more for porting bare castings than the entire heads are being sold for by TSP and others.

You cannot tell me that TSP heads are even CLOSE in performance to heads worked over with the likes of Greg Good, Joe Mendelis, or Larry Meaux.. it's just not happening. The only saving grace on budget heads is just that, they're cheap.


And Aaron, you seem to smart for this site, where do you usually read and post? PM me..

First off, I do not believe for a second you are making 461 rwtq with pump gas through a 12 bolt NA. I'm going to say someone's dyno lied to you.

Why do they sell the **** out their heads? Because they're cheap, and they are a sponsor here. Bang for the buck is one thing. Performance is another. If they know their ****, I can give you a long list of people who must have invented racing from scratch. Guys like you brag about their performance because you can't see through all smoke here on LS1Toke and don't know any better.

You said it yourself, "speed costs, how fast do you want to go" Obviously you didn't want to go as fast as you could.

Has anyone ever seen an aftermarket casting of any brand break apart at the rocker boss? I haven't, but I can't say the same for ported stock castings.

now what happens when the guys with the budet parts run faster than the guys with the expensive parts and make just bout the same power or more with the budget parts....

Lswndr, can u post a graph. Because 461rwtq is a lot thru a 12 bolt. I can believe 416 if it was a typo, but not 461. Also, what are your track times.

I made 2 qualifiers in my challenge. First was untouched heads, and the second was no dyno tricks. Those heads he used had both additional valve work and chamber work. Additionally, the weather station on that dyno was "malfunctioning", skewing the results. Somehow I knew this one AND ONLY example would turn up...

I got rid of my $2500 set of GTP stage 2.5 heads (older heads hand ported by Craig) for the PRCs.

Edit: I'm not claiming the PRCs are better than AFR by any means. I just think you need not discount some of the ported stock castings like you do. A $1100 ported truck head like I've got has my 346" 3700lb tank trapping 124-125mph.

well on a CAM ONLY 232/234 car with a LS6 intake what would make more power
ls6 intake with, out of the box afr 205/ tfs 215 heads
or
92/92 intake with some prc stage 2.5 5.3l heads

both come out around the same

bad6as

iTrader: (17)

well the 92/92 and 5.3l are cheaper
tsp has the heads for $1049 if you have your own valve springs and i do
tsp fast 92 and the ptm 92 throttle body is $1099

tsp has the afr 205's for $2285

save 137 with teh heads and intake

I have the 205 AFR heads on my motor from Jan of 2005, and in the middle of 2007 I noticed a couple of my valves showing wear on the tip. I emailed a picture of the problem to AFR and they paid for all repairs, gaskets ,and all new valves. They went way above my expectations of helping me with fixing the problem. So besides being a high quality product, they have exceptional customer support.
