trying to figure out if it is better to build the f 2.2 in my car or run a lower f2.3 vtec bottom end...used for circle track racing and weight plays a big role...

 

topic says f22 and h23 while your description says f22 and f23.

regardless i dont think there is a huge difference in the block weights. f23/h23 probably weight a little more but i dont think it would make much of a difference

 

Weight of just the bottom ends should be within 5lbs of each other
