Finally was able to install the new to me 3FE exhaust manifolds to replace the worn out stock manifold.
Lapped intake and exhaust to verify flatness to within .002"
Epoxied some portions of hardened steel washers to the intake to match the exhaust manifold thickness. I could have machined the exhaust manifolds to match the intake, but would rather maintain the thickness of them. It was a simple task to hand grind and epoxy the washers to the intake. Verified they all matched each other with .001
Welded up hole in the stock EGR fitting and installed with a new copper crush washer.
Was able to use the factory heat shields with my "F" intake, tight but they fit. Assembled with all new studs, hardened steel washers and flange nuts.
Next up is to get a 90 degree fitting to redirect / keep oil line away from rear exhaust manifold.
then get a new exhaust fabbed. Am planning on going with a 2 1/2" system after merge collector.
Once new exhaust complete I am going to remove the Weber and install the original Asian carb and factory air cleaner.
Having no fun locating the compression nuts for the stock carb fuel lines, my local Toyota dealer is less than helpful, will be ordering online I guess.
Also the Weber adapters do suck, had a heck of time getting them sealed, but was able to eventually.
