    I put the same thing on my truck, not sure what gaskets were used and all that but somewhere around 10k miles the chain tensioner turned loose on the driver's side head and let the chain slap around and actually tore a hole in the valve cover. Hopefully that was just a fluke.

    I don’t remember the exact numbers but it wasn’t much. I was disappointed too. The only reason I swapped heads was because I had the wonderful 4 thread heads and kept blowing plugs out, 3 to be exact. I can’t find any of my dyno sheets right now if I do find them I’ll post the numbers. Let me know what you make after porting them.
