where can I find any info???????, jdm 7afe head Options

[dans_st]

I recently bought a JDM 7afe head and I am planning on swapping onto my 7af(t)e, I just cannot find any info on what to do since the JDM 7AFE does not have a distributor, I have tried searchin, and all I find is "JDM 3SGTE" stuff.
I would like any information I can get, I am not too concerned with the loss of EGR as my car is not using it right now anyways I just have a resistor on it and it seem fine.
I have also heard that I can use a ford EDIS system, what do I have to do to do this, I do not want to got over to a standalone, I currently am just running stock ECU with SAFC-II and plan to either looking into PROM tuning or if I cannot do that possibly go to E-manage ultimate.

Also is has anyone ever looked into siamesing the intake/head ports on intake side, I have done this on my 350 TPI Camaro, and it has really raised my powerband and output and the runners are very similar.I lost some torque output but am willing to do so to gain some higher RPM HP.

this is part of a long term project just I am trying to get as much info as I can.
thanks for your help

Unless you have an even port from the manifold to the head... it wouldn't matter too much, IMO. To me, it's just not a practical way to go about it. Why not just port out the old USDM head? I think that way you can at least physically control the way you want air to flow. With the dual runner head, there's a chunk of metal that acts as a restrictor between the two inlets. Unless that is cut away... I don't see this idea as being very practical.

I actually was planning on cutting away the center, so that I had One larger runner(wider), and I do realize that iti s not very practical, but I can TIG the peices in and then port the passage out.
I am running a GT32 turbo (which is a little too big-i know), and I want to get higher flow to get some higher #'s and hopefully get it to spoll sooner also. I know that my throttle resonse will possibly suffer somwhat, but I don't mind it if I can get more power from my engine.
I am just really trying to get as much out of my 7A as possible without going ove to the 4A head. I plan on going over to the 3SGTE in a year or so I am just try9ing to experiment with this right now since no one has ever tried it.

And I do agree that the TVIS will be a restricion and it must come off to siamese the runners anyways, so that is definately getting taken out.
What I hope will get more power is since the two inatke runners will be opened up I can also port the head that much larger as well which will give me a much larger injtake port(on head) than the single runner could ever offer.
