Does the LS2 throttle body fit on the LS3 manifold Epstein

Personally prefer the 243 heads. Smaller ports provide faster airflow at lower rpm. They seem a bit more seat in the pants off the line. Have experiences with both and yes, the l92 heads are more of a dyno queen for numbers... depends what trying to achieve. Small cam, wanting broard torque- go the 243s! Engine feels more refined imo
