Ok... got my TEA Stage II 5.3L heads and here's the numbers:
lift - exh - int
.100 53 66
.200 113 133
.300 165 197
.400 209 249
.500 251 296
.600 258 301

The exhaust side seems to really flow well (as does the intake side)... given this would I be better going more duration on the intake side?

I was originally planning on a TR224 cam... but now I'm thinking maybe the TR 227 reverse split may be better? What do you guys think?

(on top of heads and cam I'm doing hardened pushrods, new lifters, are oil pump, double timing chain, LS6 intake manifold, ported Throttle body and ported MAF)

Numbers do look nice.

I really think the TR-227/224 would be a little more powerful than the TR-224/224 if there aren't any P to V clearance issues. If the heads were only decked for clean up, I would think the 227 should be ok.

I used a Comp XER with my TEA 4.8 heads. 224/112/581. Got it from Speed Inc. Runs strong, idles great, nice lope. Good combination.

I have a very similar 224 XE-R on order with SRP!

What did your car dyno? I have TEA 5.3 heads

Another reason I don't put too much stock in dyno numbers. I'm sure if I dynoed again it would be in the 42X hp range. ET's are what matter to me. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Before I purchase I cam I'd like more opinions... w/these heads would I Make more power with more intake duration?

Well you know I dyno'd 415rwhp with my current heads in my sig with the 232/226 XE-R cam.. This was untuned.. Right now I have the F4 cam from Futral Motorsports and once she is tuned I will post dyno #'s.. I am hoping to pick up more midrange horsepower secondary to going with the smaller cam..

Here are the flow numbers with the LS1 and LS6 intake for my TEA Stage 2 5.3 heads very similar to the ones you have.

Lift LS1 LS6
.100 65.14 65.6
.200 133.1 133.5
.300 184.3 189.9
.400 217.1 227.75
.450 229.2 241.3
.500 236.3 250.2
.550 236.3 247.5
.600 235.7 245.18

As you can see the LS6 is better. But the numbers are real low when the intake manifold is on.

JMHO
Looks to me like the intake side needs all the help it can get! The reason of course is that restrictive LS6 intake. We have great heads TEA made better but we still need an intake that can keep up with the heads!

If you have the P to V clearance think about a Comp Cams XE-R 228/224 or 227/224 etc. The Comp Cams lobe will flow about 1-2 percent more than a Thunder lobe so you might gain a few hp over a similar TR cam. With the XE-R's high lift it might be too tight, if that's the case, I'd think about a Comp Cams 224/224 XE-R or TR-227/224

P/V is the key in your case. I think you will make good #'s as long as you stick with the norm.. I like going outside the norm and I tried a much bigger cam, but I do not have to worry about P/V at this time.. I would suggest staying with 226 or below..
