Dan,
I thought about just replacing the lifters, pushrods and rocker arms to make sure there is minimal lash in the upper end of the motor which can occur as the rocker tips wear down and lifters pick up gunk. I thought about replacing the oil pump with one of the modified oil pumps that helps addressing the oiling issues. If I recall, these are also sold by Tom and the holes are drilled out to deal with an alignment problem from the factory. I get really nervous driving a car going on fifty years old with what I'm sure is the original oil pump and I'm sure the screen has never been cleaned out.
The roller rockers, cam and timeing set are all wish list items that I'd add if money still permits. I also have a sagging coil on the rear drivers side that needs replaced, a crack in the dash ($600 - Just Dashes) and my rocker trim really needs a face lift (anyone have a really nice set for sale?).
Just a few touches to turn an already nice car into a really nice car. :)
Chris
