Okay,
HERE is Flashblue's thread containing the
DOHC Head Swap Parts List, and a bit of discussion...
(mostly just this Forum's regulars taking digs at one-another) 

Here's the profile for
FlashBlueRS, from which you can check into his other posts.....
just don't bug the guy with n00b Q's until you've read into things a bit. 
Honestly, I don't know how this escaped me before now. I've done my fair share of
Searching, including checking posts by those I know have done this....
I guess I'd focused on the apparent "pioneer",
DNS-EN.

Thanks again for steering me right,
gst4g64!!
I'll emphasize that all three above members can and have been a great resource to our community, so please read their posts before burying them in questions they've likely posted answers to!
I'm going to continue compiling data in this thread, regardless of all the other threads showing how "it's already been done".
Just consider this my contribution and best attempt at "merging" all relevant threads and info I can find... without actually having the abilities a
Moderator would have in doing so!

I'm not ready to take on this project quite yet, so I'll log my research as much as possible....... even to the most basic of information and its sources.
......now I've got to

, so more notes and links will follow later.
EDIT:
One more link before I get to bed for a bit.
____/\ That's actually one of Flash's posts from the first thread linked in THIS post, but I thought I should give it some
emphasis.
I'd read some of that info he linked before, though it was a bit over my head at the time.... thus the research and my need to "get back to basics"!
