Does anyone have any information or input on these heads for TB.
I see alot of people running the GN1 head, and yet if you compare the numbers the T/A heads are better for approx the same money. I did a turbobuick search for t/a heads and came up empty

So what's being done? Are the runners welded or cast much, much higher under the valve cover area and ported to the max? You can only get so wide between the push rods so going with a taller port must be it.
