I have done some research and have come to a conclusion that maybe some Stage 2 243 casting LS6 heads would do me good. I need to gain some low end tq. My Hp/TQ numbers with my cam are in my sig.. Again i want to get some low end tq back. With this cam i have a DCR of 8.2. I was thinking when i do a head swap get some thinnner head gasket to raise the DCR up a couple of points.

So what else could benefit me?

Thanks

the thinner gaskets will help. if the cc on the other heads you are thinking about putting on is 64cc that will help out some more so it should be a noticeable increase.

I am actually thinking of going with some Ported 5.3's..

I've seen a lot of AFR head combo's with that cam if you have the cash. Then mill and run a thinner head gasket until you get the compression you want.

+1 for AFR 205's. Those heads by design will produce more torque and throttle response than a ported stock casting. The smaller runners have greater velocity at all lifts when compared to a 220-230 cc ported head.

If your budget doesn't allow for that, I'd look for the best flowing 5.3 heads with the smallest possible port, before looking at LS6 style heads.

My vote is for the ETP/RHS heads. With a unported Fast 90 & ported LS2 TB on my cousins Corvette with the 225cc heads, made 444.97 RWHP(0.97 correction factor) & 405.74 RWTQ SAE corrected (would have uploaded a zip file of this but it was to big). The cam in the car was a 238/238, 112+4, .578"/.578" lift w/Jesel shaft mounts, and stock 93k bottom end. He had 1 3/4" primary headers, Kook's 3" X-pipe w/cats, and TPIS cat back exhuast. The stock rods didn't live to long after the upgrades. Here is his new 402 stroker with the same heads, intake (ported now), TB, X-pipe, and TPIS cat back: https://ls1tech.com/forums/dynamometer-results-comparisons/869674-our-latest-403-532-rwhp-491-tq.html

I do not know too much about heads, so what kind of cc on the heads am i looking to get?

How much will a set of AFR 205s run? And what cc are these heads?

I ahve talked to you a lot in the past so i trust ya... Just need to raise my DCR and get soem TQ back

AFR=$2300 and 205cc intake runner (like a stock LS1 head). Sounds like the cheapest fix might be to bump up your compression by running a thinner gasket and fly cutting if necessary to get ur DCR in the 8.7 range. Don't be intimidated by flycutting. There are several on here who i am sure will loan/rent you a tool and walk you through it.
On second thought, PRC (TSP) will mill your heads to desired level and recess the valves if necessary to run that cam or bigger w/o flycutting just to give you another option. AFR's have better ptv clearance than stock to help you clear and if $$$ is no object might make you the most power. You will need to mill these down to 59 or 60 cc chamber to reach your desired SCR but i believe it is no problem with a cam of your size. Just some things to think about. Let us know what you decide!!

I would go with the Trick Flows if I was going with heads, I'm not a very big fan of AFR but a lot of people are and I myself have been saving to go with Trick Flows heads. But more compression will also give more TQ as has been said, a thinner head gasket with your stock heads or a decked set of heads would gain TQ also as been said above.

With the camshaft you've selected you definately have some room for decking & extra compression. I'd look to something with smaller runners to help out the torque a little bit. We sell the PRC Stage 2.5 5.3l heads with approx. 220cc runners. For someone wanting a awesome value head with big power output these are hard to beat! We can deck the cylinder heads for extra compression & you can add a thinner gasket for better quench/compression!

You should be able to mill the heads down to around 60cc and run a .040 gasket with that cam and have plenty of room and extra compression. I would flycut the piston tops too.

Have you thought about rear gears?

I've got the same cam as you except mines a 110+1. I've been wanting to get some heads also but ended up getting some new CCW's instead. Whenever I do they'll probably be AFR 205's or some Trickflows. I know the AFR's would really help down lower in the powerband where you could take advantage of it in everyday driving, Trickflows probably would too but would cost a little more in the end. I'm curious to see what your final results would be with either of these heads.

I would save for a set of trickflows, but if money "is" an object to your new daddy azz, then go with the patriots IMHO!

Which flow #'s for a head...the low low lift or the high lift make the most difference in torque and power under the curve.

Hey Jason... You are actually the guy i ordered my cam through

Aren't the 220cc runners a little too big for my stock cubin inch motor? Is decking and milling the same thing? If i were to do that, and i went with .040 head gaskets what SCR and DCR am i looking at?

Hey Brad, long time no talk.... How ya been hows the car?? What heads are you talking about? It is wither going to be the 5.3 heads or AFR 205s..... I think i need smaller runers like in the 205 range.. Will the 220cc runners be to big for my stock motor? And what does the 60cc do? What exactly does fly cutting do? I have a small enough cam where i think i will be able to get away with not having to fly cut????

yes i will, but i also need to get a 9"

if you go from the stock 66.6x cc combustion chamber and stock gaskets to a 64cc head (like the stock ls6 heads are) and use an .040 gasket your dcr will be around 8.8 if your cam is exactly what it says it is but alot of times the comp cams are slightly bigger than they say they are so you should be ok on 93. it's always a good idea to check but i would think that cam should easily clear without flycutting on unmilled or slightly milled heads. you should be around 395-405 rwtq with the bump in dcr and better heads.

I am sure that my cam is bigger, i never did do the cam doctor. i do have my cam card from TSP though. it would be nice to have a higher DCR.. i will be doing wither AFR or 5.3 heads. what are the cc on the cobustion chambers on those 2 heads? I will always use 93 with my car... i would love to get 395-405 RWTQ..... and of course some added hp
