Your question isn't entirely understandable.
Are you needing the cylinder head bolt torque specifications?
And are you timing the valves or timing the ignition?
If you're at all interested in getting the shop manual, here is the link for a brand spankin' new one that is actually less money than the ones I've seen on ebay recently. $43 + ship n tax.

You can also get by with an older B100/B75 manual to do most repairs. I see those on craigslist all the time for less than $20. You just wouldn't have the BF8A supplement that describes the few differences. But they are few and the valve tapped clearance is the only specification that isn't the same as the other two.
