certain aspects of my porting and the same with my welding (mainly aesthetics) i keep to myself as its taken me 8 years to get to the level im at now and i learned on my own with trial and error over that span of time with no help. i also do this as a side gig so to just go out and tell everyone how to do it doesnt make sense. its all basic stuff i use for the porting.... carbides and cartridge rolls...... its the tooling and technique for the finish on the ports is what i keep proprietary.
its not only the tooling.... theres lots of patience to be had doing this, theres 20 hours in these 2 heads lone and thats without messing with the combo chambers. throw in another 5-8 hours for those.
Patience does work...lol Understandable about your experience and some of your trade secrets
I have like 7 hours in mine, but I only touched a few areas though not every part. Porting the combustion chamber should be fun for me...
These intake ports on these subaru's are pretty easy, but I agree the dog leg is a kinky pain in the rear
