I've got a 09 5.3 Yukon that has BTR DOD delete kit installed, all new ls7 lifters, stock ls2 cam along with LS6 valve springs. Heads are unmilled. Can you tell me if I'd need to run a different length pushrods by chance? I am getting a loud tapping/ticking noise at idle and it does go up with rpm and unsure if it's a lifter not priming or possibly wrong length pushrods as I have seen both cause similar issues. Lifters soaked in oil for 2 days prior to install. Thanks for any help..

You need hardened pushrods, buy a push rod length checker to verify length.

It's best to measure, always.

Make sure you check for exhaust leaks.
