I am currently have the stock heads off my car due to the fact that I am getting a spark plug socket fixed. My question is what is your opinion on putting the stock heads back on the car or putting a set of ported LS6 heads on instead. I currently have an LS6 intake and QTP headers on the car. I have no plans to install a cam. I am getting my headers and intake coated and do not want to take the motor this far apart again. This would be the only time I would do this at. So if I could get some opinions on which way to go it would be helpful.

Thanks,
Steve

 

You will gain power but not as much as you can. The factory cam will not take full advantage of the heads
