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

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
