There's photos, unorganzied, at the bottom of http://wps.com/AMC/Navarro-parts-bought/index.html
THe heads are pretty damned interesting. Over the weekend I'll do some side-by-side pix of a stock (70) head and these two oddballs.
The R&D head is most interesting. It's a very pretty casting, no flash, clean (dusty) no rust nicks or dings. It's got O-ring grooves, Ive got boxes of O-rings (steel, and rubber). The manifold banged around a bit on the shelf, but it's cast stainless so no big deal there. I also have a 6-port fuel distributor, camshaft-mounted oil pump, external water pump. Valve cover with welded-up oil filler. Custom timing covers (two) plus NOS-appearing factory. Factory head gaskets plus others. A ton of headbolts. New bearing sets. Pistons, used, but clean-looking.
I assume Navarro made one or more non-Indy turbo motors, but I've never heard of them (nor have I looked; I suppose I should). Barney just had surgery yesterday, someone said; maybe if I'm polite I can go talk to him and get the "real" story (as if memories were facts...)
I've got a stock 258 and A904 in my Hornet, but now I'm thinking that building a reasonable turbo/FI motor, a 199 or whatever this block is, if it's any good, and put in front of the T14/OD I have, might be super-sweet. The manifold is drilled for some mechanical FI setup, but I suppose could be hacked for modern injectors. It's all fantasy at this point.
I left out of the web page that I haven't hauled it all home yet; I drove there in my Hornet, and only got to load stuff into the trunk; I took stuff that might "walk off". THere are a bunch of other items I'll eBay for (big) pocket change, like new-in-box 1960's Stweart-Warner tachs, some SW gauges with Navarro mods, new "stylish" mirror new in box, etc.
TOmorrow I'll pick up the block, "stock" head, valve covers, oil pan, the scored crank and bazillion engine parts. THe other head is massively ported, that much was obvious, and it was super clean or not used. News at 11.
