I have a 2005 head from a 185 motor, I know the valves are junk and I have newer ones. I need a block so I'm not sure what year i'll end up with 2002-2009?

1. If I remove the restrictors on the pre 06 blocks and use my 06 rocker shaft can I straight up use the 05 head or is there something i'm missing? I know I'll have to drill a 1/2" hole behind the balancer gear on the pre 06 blocks.

2. On an 06+ block can I use the 05 head and use the 06+ rocker shaft?
