Here's a link to an article on building a 261
http://www.inliners.org./tech/261_build.htm This was published in our club
newsletter a while back.

1) I don't know. Even the different 261 model years had running changes to
the rocker arm oiling feed. I would leave well enough alone.
2) see picture on Inliners link.
3) Find a freeze plug to fit the block where the draft tube goes. Drill a
hole to fit a PCV valve from a 250 Chevy.
4) Yes
5) Good luck finding new 261 rods, or even new rod bolts for that matter.
Have your old rods sized and              reconditioned. Check Stovebolt.com
archives for the 411 on hydraulic lifters. I would use solid lifters (as
original) rather than modifying hydraulics.
