What Manifolds are these from??? A-series?? Twin SU's...

[BURLEIGH]

Please help me identify these manifolds.  I'm pretty sure they are A-series, but I don't know specific years and heads they fit... I am a long time S30 guy and can tell you just about anything you want to know about first gen Zcars, but these 4 bangers are relatively new to me...  I have these for sale and I don't want to sell someone the wrong part for thier application.  Any help you guys can offer is much appreciated.

 

Her are a few pics of the manifolds in question:

Thanks in Advance!

The first almost looks like a Triumph manifold. Is the hardware SAE or metric?

 

The third manifold looks like a roadster R16 manifold.

Everything on it seems to be metric...

 

Thanks!

Yep!  Looks like the first one is from a triumph... Glad I researched, 'cause the guy I got it from had writen on it " DAT 1800 s head"... I wasn't sure what that was, but it was obviously WRONG!  It had Hitachi carbs on it though... :-)

 

Thanks Again!

I wonder how close (or not) the ports on the R16 intake are to that of a round port A series. There seem to be a ton of R manifolds out there, and with a welder and an hour someone could make it fit their A series...if the port spacing and size is close.
