I would like to see how these heads perform at their max porting capability...
And how in the heck did you get it to run 162 to 142 degrees? That's cold! Can those even be real world temperatures? Isn't normal like 180 to 200 when it's in the car??
My car runs best around 120* at the starting line! (360/OEM heads)
Just gotta experiment and set the carb up accordingly.
But that's after the engine has been "heat soaked" - warmed up and cooled before going to the line.
If not careful, it will fall on its face.
Nice heads though! I've been keeping up with the latest on them.
