I'm sorry I have no idea, but I wanted to ask why they wanted to do this? I thought the point was to get better flowing heads, not more restrictive? I know we used to use 305 heads on 350s to build compression. Do 5.3 heads on a 6.0 do the same thing? Not trying to be a smart ass, just curious. For what it's worth I thought I read somewhere recently that you could go up in heads on blocks, but not backwards. Example: 6.2 heads on 5.3, but not 5.3 heads on 6.2.
