Do I use the new doughnut gasket that came with the DP and the new sping loaded bolts to put this DP on, or do I use the stock pieces? I only have the stock O2 housing if that makes any difference. Also, should I put some sort of lock-tite on the bolts when I put them back on? In the service manual it list 4 ft-lb to hold these bolts in.

Any hints would be helpful!

Thanks!
