I see the timing for 34* and the dominator fine on my small block. I may send it to Dom to check it out. Maybe he can run it on his 472.

TTI coatings are junk.

The ceramic has some surface rust showing...the car gets caught in the rain every now and then, but is never put away wet.

Also had a chromed set that were not supposed to rust...well, they rusted out nearly...

Regardless of who coats your headers, you NEVER want to break in an engine, or dyno an engine with a with a set of polished ceramic headers. Polished ceramic is only rated at 1000F - 1100F metal temp which translates to around 1200F -1400F EGT. Improper fuel or timing will dull out a set of polished headers in literally a minute or two. Once they get hot enough to dull, the pores open on the surface of the coating and the headers will begin to get rust spotting shortly after. The headers below had a 2000F thermal barrier on the ID and still dulled in a few minutes due to a lean start scenario....

If they're coated with a high temp ceramic, i.e. 1800F - 2000F this isn't generally a problem.

aka order them black or unpolished if you plan on driving it!

ok, that's not a real problem for me. I thought they are too shinny anyways. I have no other choice. only set of headers I have.
