Cracked intake manifold

I got a 305 small block in my 86 GMC Wrangler and I cracked the intake manifold while doing a rebuild, I don't want to go get a new one, JB weld high heat doesn't seem to be doing the trick, any suggestions??

Take it to a shop and have them weld it back up

I had to look into that as well. Autoweek has a full section on that. It seems to be an option package (like Scottsdale) which was common in the great white north for about a decade before Nash-Rambler decided to try it as a way to market what they inherited from Kaiser.
