I used JB weld on my intake and ran it for a couple of years on the street and at the track without any problem. I had the intake off fairly frequently and was able to keep an eye on it. I was surprised at how well the stuff adhered. I used it for port-matching purposes on the roof and directing air past the pushrod bulges on ports 1,7,2,8 which actually gives you a narrower port opening on these ports. You can read about this modification in Pete McCarthy's 'Pontiac Racers Handbook'. They did it on a Nash but I figured it would work on an old Torker. As you can see in the larger of the two photos, the epoxy is just starting to lift...but remember this is after driving and racing it regularly for 2 years and occasionaly for a couple of more years. If I use the manifold again I will knock out the old stuff and put some new stuff in but for now plans are to run a 1st design Wenzler
