Looking for rebuild advise

How exactly does recurving a distributor work? could I learn to do this and practice on an old one first? also, Dutra does dual exhaust doesn't he? Edit: Also, got to thinking, can I do any refinishing work myself? the lifters? etc..?

Ping BigSlant6Fan on slantsix.org - he sells (used to sell?) recurve spring kits:

Doug Dutra does Dutra duals (and Dual Dutra Duals, and oil pumps with hardened gears, and headwork, and... :-))
