Port molding. 3D model of your porting work

I would never sale my flowbench. My 29 year old son loves to race but has zero interest in porting heads. I even paid for him to go to Darren Morgan’s two day porting theory class hoping he would get interested. Maybe someday he will after I’m dead and gone. Lol.
That’s because he has you, DAD! The master, the head porter extraordinaire!
Keep good notes just in case he becomes interested in it one day. My son may need his skills. ;)
