Building an intake short radius...


for a larger version - https://gallery.ostportworks.com/displayimage.php?pid=3528&fullsize=1
and an exhaust short radius....

changing the radius shape of the intake ports yields more flow...

Finding room in the exhaust bowls for more flow.....

Not to be left out, the exhaust ports saw extensive re-shaping

As is with every head I do... the chambers are fully deshrouded, with all the sharp edges removed....

The head will be receiving a fresh 3 angle valve job, along with back cut intake valves, and new viton rubber valve seals. As mentioned - this head with the original springs is selling for $1600.
