Which are the better heads for a car that is a weekend driver and sometimes during the week depending on weather. I was looking at patriots stage 2 LS6 heads, but read that swapping to 5.3 heads immediately add hp b/c it raises the compression ratio?

The LS6's flow better, you can just mill them too if you want to up compression. If I had to take a stock LS6 vs stock 5.3, id go with the LS6.
