LT1 Heads on a LT9 Block...

Does anyone know what/if mods need/can be done to make the LT1 heads work with a LT9/LO5 block?

I have done a search and think I know the answer...but just curious if anyone has some solid info...thanks.

If those blocks are GenI then it would be the same mods for any GenI SBC.

They are Gen 1 SBC engines, used in trucks. The LT1 heads will not work unless you relocate the coolant passages.
