Ok so I'm going to be installing a set of headers on my 981. The engine block in the 981/9a1 engine is a monolithic-alusil (alloy) and the headers are T304L stainless steel. I know I could probably just use a new set of oem bolts, but was thinking I'd run some manifold studs instead. Silverlake project makes Titanium and Inconel. The ti are apparently rolled. So hoping for less chance of galling. From anyone's experience here, what is my best chance of material not seizing in the block? The Ti or Inconel ? And Is nickel anti-seize still my best bet for this application? Fwiw, this motor does get pretty hot in comparison to others. I know inconel may be overkill from a temperature standpoint, but again, more concerned about seizing than anything else. (I'm also probably overthinking this whole thing and either is probably ok, isnt it lol)

Sometimes it is possible to spend less money and end up with a superior product for the application. The "Stage 8" locking header bolts are hard to beat and are stainless steel.
Inconel and Ni anti-seize. Stronger and more uniform heat transfer.
Thanks for the replies so far guys. I should've linked to the product page for better reference. The ti is Ti6Al4V alloy and the inconel is 718. their tech section shows the following graphs for tensile and yield strength....

Ultimate tensile & yield strengths Ultimate tensile strength measures the maximum stress a metal can withstand while being stretched before breaking; in other words, it is measured as the tensile load required to fracture something. Some metals can break sharply, while some others will deform or...

Iconel is just a tough alloy.
