TSP Stg 2.5 LS6 Heads vs. Stg 2.5R 5.3l Heads for my set-up? Did a search and did not come up with any good info, I am not really looking for power under the curve here, I already have a 233/239 112 cam and now I need some heads, which ones would suit my needs and get me more power?

or
TSP Stg 2.5 5.3l Heads
I do not want to flycut and more compression would be nice. Thanks in advance

I just finished making the exact same decision. There seems to be a TON of people running the 5.3L heads and most of those people have had very positive results....I ended up going with the 5.3's milled to 60 cc. From the flow data, it looks like the LS6 heads flow a bit better up top and would probably net you a few more HP up top, however I was more comfortable with the 5.3's simply because there was more information available on them.
As for the flycutting question, I'd contact TSP and hopefully they can give you some guidance there.

I agree, thats not the way to plan for your ride. You always want the best power under the curve, otherwise youl only have fun at redline only.

I have the stage 2.5 5.3 heads with a custom pat G cam 232/238 6xx 6xx 111LSA+2
No flycut needed..In an A4 I put down 435rwhp 407rwt..My old numbers with a 224cam was 417rwhp 407rwt..I thought I would lose lowend going with this cam but it does not feel much different down low..It screams mid range and up top LOL!!!

There are plenty of guys in the dyno section running the MS3 w/the 2.5 5.3 heads w/no flycutting needed. Even Johnjanz@texasspeed is running that combo and states no flycutting required... Go for the 5.3's. That's my next investment
