I've been running the Dialynx but, with the flow bottlenecks still
choking my system, I can't report one way or the other on
performance yet. However, I can tell you (a) it is built like a
brick shit house, (b) you have to do a little "custom" grinding
to get it to clear the intake manifold and (c) it will warp like
a wet board and you'll have to take it off and re-face it at least
I haven't seen the two-piece, but I think that would be worth
a look in order to get away from the thermal stress/cracking
problems inherent in that oh-so-long hunk of I5 cast iron.
