    706 Heads??

    Are my stock 5.3 706 heads worth anything to use for a build or should I just turn them into door openers?

    If you have them worked well they will bump the compression on your 6.0.

    You must have not seen the foreign porn link that was up there a few days ago. I read the LS1TECH thread and it was very relevant and informative.
