Poly Engine what was good/bad about it and why is the LA better?

Great looking poly! What headers are those? Also, what cam are you running? Thx.
The headers are custom made. Tried to get them to match up to the stock exit locations. In hindsight, I would have done the passenger side differently.
The cam is from Camcraft. 224/224 @.050" solid .450" lift. 110 degree lobe separation 106 ICL. Very flat torque curve. Over 300 lb/ft from 3000 to 4500 rpm and still pulls hard on the top end.
