while the topic did stray a little into a price thing, that shouldnt take away from the fact that these are pretty nice heads.
but as nice as they are, and as happy as Wize is that he bought them....im going to go out on a limb here and say i dont think he would own this set of heads if he had to pay $4200/pr for the bare castings.
for that same $4200....i bought some 440-1's set up for a Jesel rocker system, the Jesel rockers, the spray bar valve covers, all the valves/springs/retainers/locks/seat cups/seals....and still had enough change to go out and have a few nice steak dinners.

granted....my 440-1's dont flow as well on the intake side as these do either....so, i guess it all boils down to how much youre willing to pay for the small runner/big flow thing.

i'll be looking forward to hearing how they end up fitting on the motor, how the valvetrain goes together...and how the motor combo works out when Wize gets it all done.
