I just had a lg G5X3 on a 114 put in my 01 Z06 with about 70k miles. It still needs to be tuned, but I have a lot of lifter rattle??? Car runs fine! Just wasnt a rattle this loud there before! Any advice from anyone??? Was reading where the lifters may not have been bled down properly???

 

You'll have describe lifter rattle a little better. I assume you changed the springs and the pushrods?

 

No push rods just new spring and the cam, and heads were never removed...
