If you are looking @ the same brand heads both Stg. 2.5 heads. I would have to say the LS6 heads are better. The 5.3's normally raise compression, but in my case with the GMPP 60 cc LS6 heads I have 11:3:1 compression.

When comparing peak flow numbers, the LS6 heads on a stock bore are going to flow ever-so-slightly better. We're talking 4-5 cfm. As mentioned, the LS6 heads will have some better flow in the mid-to-upper lift range. Whether or not they're worth the extra money depends on what you're looking to do with the car, what size engine you're going to be running, camshaft, etc.
