What size push rods do i need? I have a 6.0L iron block with stage II heads that were shaved 12 thousands. I have a set of hardened pushrods from Thunder 7.4, but I got them before i found out that the heads needed to be shaved. Will these still work, or will i need smaller?

You prolly will need shorter ones unless you have adj. rockers, even then you still will prolly need a diff. length. Borrow or buy the pushrod length checker and get the correct lenght. I did a bunch of guessing and ended up with 7.035 pushrod length, but I have about three sets of longer lengths before I got it correct.

Thanks, I thought about getting a pushrod checker, because after the post, I installed a pair of Harland's and when i hit zero preload, i still had to turn the burn the bolt several turns before it bottomed out. I think I may need correct pushrod length to determin how much shims I will need.
