Hiya, glad you got the mount ok!
I have seriously bored out the ports on these heads to find out just how much material exists between the ports and water jackets and theres no way youll ever break through if you just follow the guide.
Ive also cut them in half to have a look.
I didnt manage to get a break through at any point so its very unlikely unless you get a casting thats got flaws in it but so far no, theres no way youll scrap the head just doing this.
Just be careful to avoid hitting the seats at all otherwise its off to the speedshop for a valve job.
If you get stuck at all, let me know.
