Don't worry Mr.2k2 I have dyno graphs comparing them for you. Give us a call & we can get you all kinds of dyno data to help with your decision.
I prefer the Stage 2.5 5.3l heads for the camshaft we're discussing. We can set you up with free milling & thinner gaskets if your looking for the max possible HP gains from this setup.

With a TR224 112+4 LSA it is not adviseable to mill the head for DCR reasons. Your 5.3L come usualy in 63cc form (mine were) and that allready put DCR in the 8.6x range wich is 91 Octane + range.
Being a single pattern cam, cylinder pressures are high, so IMO from experience, I recommend unmilled, stock gasket if that cam is to be run at 108 ICL. Ramp rate on TR 224 lobes is 50 variation

/\ agree with predator-z. I have the 5.3's milled .030, stock gaskets I need to flycut to go any bigger with a cam.
out of the box 5.3's with a 230's plus cam would be awesome

This isn't really a max effort drag car, more like a fun street car, as I said it goes to the track once a year, the rest of the time it's a poker run here, and a show there, the occasional parade duty
Now the other fbody I got will more likely be the max effort street/strip setup
Thanks for your help gentlemen, I think I will go with Predators reccomendation of unmilled 5.3's, given the best octane rating around here is 91

This is a completely inaccurate statement. We actually make more on LS6 heads than 5.3l heads. This is a good example of someone with no actual knowledge about us making a B.S. statement.
The reason we typically like the Stage 2.5 5.3l head is:
The reason we typically like the Stage 2.5 5.3l head is:
- CHEAPER THAN STAGE 1 LS6 HEADS WHEN YOU GET A SPRING KIT
- ENGINE DYNO TESTING SHOWS BETTER POWER GAINS COMPARED TO 2" VALVE LS6
- CUSTOMER GETS STAINLESS / LARGER VALVES FOR LESS MONEY!!
i was told this BY *********** at TSP.. im not making some blatant statement and do have a clue what i am talking about.... if that is not true than maybe you need to feel some of your own guys in..

Please forgive me for being so aggressive about this, but you have to understand a few things. We spend way way more time & money developing & testing our combos than anyone else on this site. The reason we recommend something is because we tested it & know it works. Making a claim that we simply prefer something because we make more money on it is just completely unfair.
I bet I spent $10,000 in the last 1.5 months testing our combos. That money was spent to make sure we provide the best products we can, and to make sure we know what combos produce the best power.
Sorry I was so aggressive, but it really hurts when someone makes a comment like that. We try way to hard to do the best for our customers, for a statement to just be thrown out like that.

Finally got the money for a set of heads and was wondering what set would be better for my T/A its got a TR 224/224 112 lsa cam in it, a set of headers/ory and a catback, and that's it as far as power mods
So which one would be better, it's primarily a show/cruise (including the hot rod power tour) car with a once a year trip to the track, other than that it stays in the garage
My primary concerns are do I need to fly cut the pistons with the cam I have, and the increase in compression (91 octane is the best we can get here) and do I have to upgrade my injectors
So all you gurus, what's your opinion

you can use the ms3 with either set of heads as far as i know....
*with the ms4 either set of those heads is going to make for a sick setup..

See this is what I thought too. Ive told a couple of my friends with auto cars to go with LS6 heads instead of 5.3's because they dont need the low end torque as they have a torque converter. I always thought the LS6 type heads higher power band would be more benificial to an auto. Am I wrong here?
