As above, I don't even think its remotely possible bc of the large valves. If it was I would've already done it...head flow.

I have a friend who did this swap. Heads and intake from a l92 onto a 5.3. He used the l92 head gaskets because the 5.3 gaskets didn't clear his valves when he matched them up. That should have been his first clue. But it wasnt. He tried to fire it up. I think he only bent a few valves before the starter couldn't turn it anymore
