What type of epoxy should I use when I port my TB?

Just like it says.
Thx

I went to NAPA and bought some JB Weld, it worked great. Just make sure to give it proper curing time and all will be well.

Pardon my ignorance ????

Can someone give details for this mod?

Go to LS1.com and look in the archives, there is a write up but it doesn't say what epoxy to use, I am now hearing that JB weld is fine.
