There is a shop called Street & Performance that offers this service, although I'm not sure of the price. Another option that I saw was steel *****. I saw someone on Ebay selling six steel ***** the same size as the runner tubes who clamed they were used in the repairing of TPI runners.

 

speaking of bent runners , i got my mechanic to install comp cam and port the heads on my 305 tpi , and now i see he dented in my left runner , he says he can fix it ,but if not he will be replacing it , looks like **** the way it is , by the way does gm still have stock tpi runners as if it still looks like **** he will buy a new left side runner , thanks

 

I don't think they do. I did see a brand new set, never used go up for auction last week.
