Have a question?

[blackSS01]

I tried a seach but I didn't get the info I needed. I can pick up 5.3 heads for nothing. How much better are they then LS1 heads. They will be ported and polished. Should I just stick to my LS1 heads and port and polish them. Which would make more power. Help would be appreciated.

A lot of big names like GMMG are making some good power out of them, but I don't know if there worth spending money compared to buying a set of aftermarket heads.
