it is much better to have the port on the head a little bigger than the intake I say run it!!!!!
Its called turbulence....I make them as smooth as
possible on the match point..... use your gasket
and match it to the larger of the two them cut on
the other.. if the head is smaller.. blend the head
about 1"in.. if the bowls havent been touched that
is the biggest improvement.. my W-5s are a touch
bigger on the bottom so I will be working on the
intake tomorrow... its about .030 off on the bottom..
its due to using a different block.. the W-2s lined
up perfect..... as they say.. a engine is a pump and
the smoother the air gets in and out the better the pump is
EDIT
the tops and sides look great...maybe its only .020
but I will partially torque everything in place
tomorrow to make sure
