What's the difference in these heads?
12564825 - 2002 LS6 head (goes for $534.60 on gmpartsdirect.com)
So what's the difference? Why does one cost almost $100 more? Which would be better/easier to put on an F-body?
Sorry if it's been asked before or if it's a dumb question...
Worst case email parts@sdpc2000.com and see what they say they told me last time...
