1975 Espada, USA version-Technical info requested...

I am not a Lambo guy.
I'm asked to look at a car.
It is a 1975, USA version Espada(series???), Air nozzles are blocked off in exhaust.

What I need to know is:
Cam timing degree information...
Intake opens at ??? BTDC, closes ???? Degs after BDC, etc
Intake and exhaust cams,
AND>>>at what clearance?
Is it .020" valve lash a-la-Ferrari???

Is there a copy/print of the distrubutor advance curve available?

Do these cars utilize R2/R1 ignition point sets with 6 lobes in the distributors?
I would like to review all this sort of info PRIOR to having the car being droppoed off...
How much magnesium is used on these?
Is it dry sump?

This is a favor to a client with whom I do several, Medium/BIG Ferrari comp cars, thus my reluctant "need" to take a look at this thing...

By all reports, it looks like a pretty decent, original-ish car...

My last Espada experience: I owned a lime green metallic "wagon", it was 1978/77(?), and was a $6K trade against motors in a Daytona and a Dino!

we called it/and used it as: "the Lambo parts running station wagon!"
We used it for the summer, did a major, and sold it for $9000.00
Everyone was happy.
Didn't get another Lambo until a periscopoe in 1980/81...another car which slipped through my fingers for a quick 20K....

Any help would be appreciated, even if it is only a referral to whomever may have the appropriate technical spec sheets,
CIAO!
