I have an lly motor that lifted the heads last year and I’m finally getting around to fixing it. I have lbz heads that I plan on using for the repair which leaves me with a few questions. First, the lly has 120k miles and the lbz had 250k miles on it, does anyone know if I would have any issues using the lly pushrods and rocker assembly in the lbz heads? And second, is there any thing specific I have to do in order to use the lbz heads? Thank you!
