This is a meticulously made stainless steel
head or manifold porting template for the Mazda 2.5L V6 KLZE
port shape. They were accurately designed in CAD and then
imported into a laser cutter for an exact port and bolt hole
alignment. I have put one on a head for test fit and it
fit perfect with no filing of holes necessary. I made the
holes so that it fits snug for exact alignment. Slop in
the holes would have lead to a sloppy alignment.
You can use one of these to port KLDE heads
to flow identically to KLZE heads (assuming you have some decent
porting skills) or you can use the template to open up the KLG4
ports to match to KLZE heads. You can also use it to do
exact port matching from KLZE to KLZE.
NOTE:
If opening up the oval port intakes to KLZE shape -care must be
taken in the rearward corners of the rear bank of runners to
keep the flange width from becoming too narrow to make a good
seal.
Also -it is recommended to cut your own
gaskets from gasket sheet material and glue them to the intake
flange to make a better seal. The metal layer type gaskets
will not make a good seal between modified oval port intakes and
square port heads.
If
you would like to purchase a template -the price is $45 plus
shipping. This price is for one
template. One template works for both sides as the head
port arrangement is symmetrical.
