opinions wanted...hand port on tfs heads? ok im debating pulling the heads again and swapping gaskets. they are tfs215's that i had for my head/ cam combo. well when i did the 416 i just slapped them back on. didnt open the chambers or anything. so im debating while i have them off again if i should have the runners opened up for the extra cubes and the chambers opened up for the larger bore. (milled to 60cc and designed for a 3.90 bore) but i wonder if the cnc program on these heads is just that good i should leave it be or have them opened up. lets here it.

from what I read on opening afr 205 chamber to a larger bore on a stock bottom end I`d say that alone is worth doing .... for opening the chambers I`ll leave that to others as I`m a guy that would put afr 225 rather than 205 on a stock cube ^_^

Opening the chambers to the bore is always a good idea to allow the maximum amount of unshrouding of the valves next to the bore wall. Though I would advise having a professional do the port work.
