318 head porting for the average joe
Hi DK,
I would grind the port inlet at an angle to meet up with thinnest point, inside the port entrance.
To get the port as wide as poss. you will need to buy or make an 'E' gauge.
I made my own with some 1/4 inch steel rod and a hobby welder.
The hardest part was making a swivel joint and I cut down an airline fitting with a 1/4 bore for this.
