these are mock up pics- never mind the hard ware...there will be no fluid heat riser under this intake

manifold faces are milled flat intake and exhaust, each mounting boss is ground/filed to match the intake bosses to w/i 5-10 thousandths. I'm feeling pretty good so far...

man those are some crappy pics!
Pics are okay!
Are you going to use flange nuts or heavy washers to increase the surface contact area on the manifolds? I think it helps to keep the manifolds flat to the head.
Looks good.

IT'S ALIVE, and it sounds great- even without the mufflers. No more exhaust leaks, lots of flow, yeah, so far, so good, I like this mod...still need to make hangers and take her on the road, then finish the pipe runs

worth it
holy pig was it worth it.....think SBC with 2 barrel carb and smogger cam. now I just gotta get some mufflers or else I'm gunna hafto make reports to the FAA, cause it sounds like a Bi-plane
about half pedal when I went from 3rd to 4th doing 60 at 3500rpms- 34" rubber 4.10 rear gear
incidently, I am running an FZJ80 rear custom width with 4.10 gears, an early FJ60 H42 and matching 34mm splitcase with stock speedo drive gear and nylon cable gear into a stock geared FJ55 speedo and the speed versus revs seem spot on. I imagine this same formula would work for anyone using a 4.11 geared speedometer with the 3.70 geared drive gear and matching nylon gear with the stock 4.10/11 gear rear end AND 34" TIRES should be rather close to speed when the speedo registers 60

So does this mean one could instal 2F headers on a 3FE?

most likely yes, but then, WHY? > the 3fe manifolds are about as flowing as the 2F headers, and a set of manifold halves can be had for about a hundo...unless you have a cracked mani and a spare set of 2F headers, it would be a fools errand.

Thanks for saving me two hundred 
I'm doing a 3FE rebuild so I have manifolds, just curious
3FE headers would be even better

I dunno, man.
3F and 3FE are the same, and I couldn't see how one could improve much on the 3Fs I had, beyond cleaning up the casting irregularities, mebbe port matching, and/or ceramic coating.
Didn't do much of anything but slight polishing and grinding down the edges of the casting, all for that extra .065 HP.
