Boris; Toyota has been very smart in the way thay designed these motors. you can buy seals that look the same from any seal place. BUT thay will be ever so slightly different in there sizing. EG; if we need a 6mm wide seal after market will only have a 5 or 7mm wide one OR we can get a seal with 40 or 42 mm I/D but we need a 41mm I/D seal Toyota a pricks like that. You will also find thet the toyota seals that you have listed above are all viton seals (high temp silicon) anda lot of place just don't stock them. the dump pipe gaskets are just from toyota no body else will supply them. use some copper coat high temp silicon and thay will not leak any way.and fingers crossed that your dumps have been made properly to fit.

if you have a few weeks to wait, check out driftmotion, a US store. Google it. They supplied me with genuine OEM gaskets and seals, I think a full kit cost me $120 delivered, great due to exchange rate.
I haven't even found dumps anywhere so I'm still looking, I need ones to suit a A70 supra chassis so dump and downpipe the only place is this ebay seller that doesn't have them listed at the moment otherwise nobody sells them.
I asked UAS but they told me they might not fit Supra, anyway I don't think UAS makes the downpipe so they are out of the question because I think the same dumps can be used just a downpipe is needed to connect from the dumps and clear everything on the a70 chassis (so will fit z20)
As for seals I might try out driftmotion.
Lew are you saying use just the high temp copper silicon or use it on both sides of the OEM gasket? I have a product called Permatex Ultra Copper but temp rating only is about 400 degrees and the dump is going to get much hotter than that.

Boris yes mate put it on both sides of the gasket that is the stuff i was thinking about. I have always used the old dump gaskets on all of the dumps i made and thay haven't leaked mate.
your dumps will need to be tucked up close to the turbos and also close to the engine as possible to go past the steering shaft and miss the alloy section of the engine mount.that is what had to be done to the dumps i made for a chaser JZX80(brendans one actually) and i think he is selling them off with the steel wheeled turbos to go to a single do a search Boris he may still have them available

Yeah they don't have everything he needs but they have some of it I guess.
I know it's not what you asked for, but you should consider doing a major service since you'll be doing so much, maybe you have done some of it or maybe you haven't. However, the 100k service kit cost only $572 according to the site which is not bad for the coin. Contained within this service kit are the following:
1 x Genuine Toyota, Timing Belt 1 x Genuine Toyota Timing Belt Idler Bearing 1 x Genuine Toyota Timing Belt Tensioner Bearing 1 x Genuine Toyota Water Pump 1 x Genuine Toyota Water Pump Drain Hose 2 x Genuine Toyota Cam Seal 1 x Genuine Toyota Crank Seal
