We can now offer our custom dyno and track proven cam grinds to go with our Cnc heads
Look out for more cam testing dyno videos where we look at stability as well as power.

I’m getting a few calls to do a Cnc program for the 12 port Holden 6 blue/black. As I already have program for the 9 port red head…
But it’s a massive job from scratch to finish. So if you would seriously be interested send me a PM.
If I get the numbers. I’ll go through the pain of bring this to life

A nice set of Dart Pro 1 23 SBC heads fresh off the CNC for a speedway engine.
We have many programs for these casting from 215 to 245cc runner

Some 18 deg chev badness on the Cnc this week. I will have 4-5 intake ports 3 ex and 3 chamber programs from 2.6-3.0 sq in at the pinch and I can put these in a few castings if they are based off the GM 363 head
If your starting a clean slate build there are many advantages to going a 18 or 15 wedge head

Time to have some fun and see what a set of Proport 23 racerpro heads sound and go like.
Thanks to the wizard Michael Brody for stirring me up

SECRET ENTRY #1 - After a 7yr break, James from Pro-Port CNC Cylinder heads, will be firing up his high RPM Camaro to come have some fun, at TWO UP!!

James is a big part of a few of our Wilby builds, in particular supplying the cylinder heads for both Junk & Brody's Gemi...

So we are beyond keen to see both him & the Camaro out of the shed!!!
