Was there any discussion of machining the shoe area to match the delta angle? If Greg thought that was causing he problem, it seems that it could be milled to match.

For straight cuts a circular saw with a carbide blade works great

Since Rewarder is gone I am building my own thru transom headers for my LS swap. The headers are almost done. Need to clean them up and paint them. My question is, do you just split the outlet water from the motor and dump it in the collectors or meter some water to the collectors and the rest overboard? They have conventional injection lines, But I can't find any info on how much water to put in the collectors to keep the hoses alive.
