Is Moroso A-B epoxy good stuff? Anything better?

Hopefully someone can help me. Porting tonight, probably the best porting I have ever done, when my fiance stops by with my little boy for a visit. They only stayed a few minutes, I went back to porting, but I was thinking of them, and for the first time in my life, I cut too deep. On the intake runner of one of my magnum heads, right at the top of the bulge. It is only a small crack, maybe a quarter of an inch long if that. You can see that it bulged the metal out in a bubble just a little bigger than the crack out towards the pushrod. I am almost done porting the freakin head...

All you head porting guys, professional or not, what is the best type of epoxy AND application techniques you have used to repair something like this? I don't have the means to have it welded/brazed/etc. It is on an intake port so it doesn't have to withstand exhaust heat. I can apply it on both sides of the metal, so I don't think I will have to worry about it coming loose. I just don't want a big oil-sucking vacuum leak.

I have read about Moroso A-B, A788 Splash Zone, and a few others. I really only have about $40 to spend, and I can order the moroso stuff tonight and probably have it monday.

Help me out!!!
