Damn those are sexy

1500 degree ceramic header paint. 5 coats. Heat shields are all black (front, rear, and crossover).

Shoulda known they'd end up red...

Sorry I was short on welding ideas earlier, we were headed to a ZZ Top concert, so my mind was elsewhere.

We just played it safe, and I ported the bare minimum on the factory welds inside. Worked out well, but to play it safer, I'm re-surfacing the flanges, and using header gaskets during reassembly.

I hope that paint matches the rest of your engine bay

You will need a new sig pic to show those babies off!

I don't think they'll show in a sig pic.

Anyway, here'* the completed pics, all fixed and finished, including porting. By tacking the outside of the flange in the pics above, I was able to port them out quite a bit by removing the inside OEM weld. I didn't take ALL of the OEM weld, but most of it. The port diameters increased from 1.35" to 1.45", an increase of 16.5" in surface (flow) area.

On a side note, my LIM manifold from the other topic about porting netted me a flow increase capability of 9% (by increasing the 1.8"x0.8" ports to the head port size of 1.9"x0.9").


Finished painting. 1500° Ceramic header paint (5 coats on manifolds, 3 coats on heatshields).



Ported out from 1.35" to 1.45". A 16% increase in area. This is the biggest restriction in the exhaust. (was)

Nice fixup Robin, that porting and paint is a nice touch

16%, baby.

WOW
Bill that looks great man.
I remember you saying a while back that you could eat off your engine bay cause it'* so clean. Thats nooo joke.

We'll see how long that header paint lasts.
