Speedmaster Small block porting tips and results Part 1
I'm not speaking for PBR
but when i did it on a 340/360 head i found the right size tube that slide right thru after a little honing to get ride of the rust flakes.
Epoxyed the tube and slide it in.
Then i had sever metal ball bearing on hand. one that fell thru and one that took a little work and the third that i had to hammer it all the way threw.
Now i feel like them tubes will never move.
Ignore all the epoxy in the intake area:)
