Just wondering if I'll need new pushrods Again if I go with ls6 heads and a mild cam... I just put crane rockers and new chromemoly pushrods in.

Depends on the cam, when you change out the lifters in the head swap they won't be the original size so you more than likely are going to have to change the pushrods again.

he doesn't need to change lifters. that's optional, not a requirement. i'm running stock lifters in my H/C car, putting down 460rwhp/410rwtq, with no issues.

to answer your question, you may have to change the length of pushrods depending on the 'cc' size of the heads and what if at all they have been milled down (also, the thickness of the head gasket used). also, the cam size as well which depending on the specs of the heads you will need to check piston to valve clearance. call around get the answer from a professional in regards to your set-up you want to run, to see if you might need to change pushrod length.

we don't have enough info to answer it with certainy.
