Got about 30 hours on the intakes went to do the exhaust, and then I seen em.. AIR PUMP PORTS. So can they be epoxied? Or do I have to braze em shut? Also, just the outside ones, or the inside ones? Thanks.

Thanks. Drill and tap the holes for a set screw that will sit below the flange surface. It's been a while since I did a set, but you might not have to drill if the hole size is right for tapping. Can't remember if it was 1/4" or 5/16".

The holes will take a 5/16th coarse tap. Thread them and put 5/16th set screws in them. I just did a set yesterday on the 360 going in my truck.

I have been doing the same to the heads that I have. I tapped 7 of them successfully using my 5/16 - 18 thread tap and then broke the tap in the hole on #8 I have now broken it off below the surface (it keeps crumbling) and resists easy removal. My next step is to use my Dremel and a tiny grinder bit to get all the rest of it out. I will use a proper pre drill bit and go up to a 3/8 - 16 tap on one hole in this head. Just a little hiccup in the process. I know better, I just wanted to hurry the process and it bit me in the A** Just heat the broken tap with a cutting torch and and give it a quick shot of oxygen. The broken tap will instantly vanish. Kevin

The broken tap will instantly vanish. Kevin I would do that if they were just cores and no great loss, but the heads had been through a machine shop, valves ground, PC stem seals on all valves etc. (the full treatment) are completely assembled and I don't want to heat the one and risk any further steps back. I will just get comfortable with the Dremel and work it out.

What about the hole inside the port? Leave it? I grind the bump down and let it go. Just keep plugging the holes like you are.

I still have a few sets of iron heads leaning against the wall in my garage but so far I have been smart enough not to touch them. I hope I stay smart enough for the rest of my life so my kids can scrap them after I'm dead.

I just used spare/old bolts. Drill/tapped, bottomed them good, ground them off & flush. Buh-bye to dat. Those ports'll never get smog hdwr on any day.

I sure did just jacked 30hrs of work.. in 30 seconds no less Just followed the advice given to me. Put a stop on the drill bit to be safe and to avoid what just happened. In my younger days I wouldn't have taken this so well. LOL. Now it's: "C'est la vie".
