TEA stage 3 5.7l or 5.3l heads? Which ones make more power? I have the 241 castings wich from my understanding makes no difference when you are porting them. I can't decide whether to just pay the core charge and get the 5.3 heads or just stick with the ones I have now. Are there any pros and cons besides the fact that you would yeild a little higher compression and clearance with the 5.3s. I just can't make my mind up.

Brian has a new port he is going to be using for the 5.7 head that looks like it will perform almost as well as a 5.3 head. But the compression ration will be slightly less.

I have heard that too. But from what I have researched, I am still going to go with their 5.3L Stage 1.5 heads, hand finished to comp level. More compression, proven performer, and you get to keep the stock heads in case you ever want to take the car back to stock (important to me). Of course, I probably won't get them for at least 2 years, so my mind could easily change.
