Another "while I'm at it" project. I was having some problems with my 240Z last summer. After driving it and stoping and trying to start it right away IT WOULD NOT START. I had to leave it at the car wash last time. I figured it was time to rebuild the carbs. My valve cover and velocity stacks are nicely polished and painted but the intake runners and carbs looked like garbage so I thought I'd fix them up at the same time. Once I pull the velocity stacks/carbs/runner off I figured I may as well pull the headers as well. Turns out the headers were a mess. The previous owner restored the car and did an amazing job but the header sucked hard. He welded metal to the top of the runners as they exit the exhaust port and left all the grapes inside and part of the port was welded over and never ground out! The two into one pipe was a disaster with holes in the welds and pipe sticking out past the flares inside further restricting exhaust flow. A friend of mine is a welder and he spent about four hours fixing it. If I knew what a mess it was I'd never have asked him to fix it if I knew he'd be using over 20 rods to get it fixed up. Anyhow he welded the flange inside and I ported everything out and it looks great. Bead blasted and repainted with Por20 and heat wraped.

This is the car when the night I bought it


After I polished the velocity stacks


New heat shield. Its stainless with a heat barrier on the bottom to deflect heat from the carbs.


Carbs removed - getting ready to pull the header.


I started porting out this exhaust port and figured I should take a picture half way through enlarging it but before I got around to taking the grapes out and rewelding it.


Everything has been welded, ported, bead blasted, painted with high temp POR 20 and just wrapped.


Sealed header wrap with DEI high temp silicone sealer to keep moisture out and mostly to keep the header wrap from flaking.


Header back in finally!
