TTI headers/valve train

[68blue]

Buying TTI polished ceramic headers for the 383 on my 68 and was told that they should not be attached to the engine during break in.

Was also told by a friend who put them on his Challenger, that this did not apply if you had a roller valve train.

Have not heard back from TTI as of yet on my inquiry about this but looked into the cost of complete roller valve train, pretty pricy, but I don't want to have to pull the engine again and scare up an extra exaust setup.

Friend said that roller valve train was a good investment but I was not sure if I really needed it for a street/strip car. Thoughts?

I'd follow TTI's advice.

I also have a set of polished TTI's on my car. Had the engine broken-in/dyno'd using a scrap pair of headers. During break-in, engine temps can be very high causing the polished ceramic finish to discolor, which will permanently ruin the finish. That's why they recommend not using them for break-in.

I have TTI on my Hemi. Please follow the TTI guidance. They know what they are doing.

Use manifolds or cheap headers for the breakin.

Have the correct info from TTI, will have to find a way to get the engine run in. That roller stuff looked interesting but a little over the top for what I wanted to do.
