i have a Storm Vulcan Block Master 85-BE
Electric drive, infinte variable speed, cuts Forwards / Backwards
4-Leg , replaceable cutter insets with 4 cutting edges per side , 8 Total
cutting edges on each insert
never had a problem with the 85 BE , mills Blocks or Heads , or
anything you can mount up
the variable speed electric drive can go from a Mirror Finish to Rough Finish,..you can set the speed to a crawl , taking 10 minutes to mill a Head
if you'd like or any other speed for a rougher/faster cut
the only real disadvantage is the 85BE mills in an arc across the Head
so in order to mill Intake sides of Heads with Lips, need to setup in Vertical Mill
it took me a Day and a half to adjust all the Bridges under the Machine,
i got the surface to .00025" accuracy anywhere on the bottom table
if you want to mill 1/2 Thousandths off a Head ...you can

this version has the largest diameter cutter wheel ever offered in the 85
17 or 18 adjustable cutters
very heavy duty rock solid Machine
the Machine mills "Dry" ..no coolant mess or cleanup
you can walk right up to the Machine and very easily, quickly mount
a Cyl Head, everythings right in front of you, easy access
the Dial Feed is really a large accurate "Micrometer" reads in thousandths and is on the money full travel
i've added a 2 inch depth Dial Indicator just to verify the Dial Feed
(see Pic..the Indicator above the Feed Handle, not the one on the Head/Wheel)
easy Leveling ..see Pic..the 1" Dial Indicator on the Wheel/Head
there were a few later versions that they moved the Motor ontop of the
Cutter wheel for direct drive, and reduced the rigidity of the swing arm , which was straighter and not as curved, but a few i've seen would have chatter marks .
also some versions SV reduce the overal height from Cutter Wheel to table by a few inches
some versions have smaller diameter wheel
some versions different Head holding fixture with different height
then there are the Head only versions (can't deck a Block, or most blocks)
SV-85BE could be vastly improved by converting to CBN inserts
