Do you have access to a decent bore scope that would allow you to look inside the bores and check out the piston tops, cylinder walls and bottom of the valves closely enough to determine if there is rust?
You technically can put new lifters on a used cam, but it's not advisable in my opinion. The cam lobes have a specific surface finish when new that is designed to help mate the lobe to the lifter during break-in. On a used cam, this surface finish has been polished and as a result you run a greater risk of having a break in, or premature cam failure. If you need new lifters, I'd opt for a new cam as well. Considering the current known state of the engine, I might be inclined to do a cam kit that includes the cam, lifters, timing chain and pushrods.
Does the engine have factory lifters with bottleneck studs on it, or has it been converted to an adjustable valvetrain?

I do plan to dig into the motor tonight, has oem bottleneck studs and nuts, I will not risk it and put in new lifters..it's looking like the cam kit is going to be in the works..I would like to keep it all original as much as I can..I drained the oil lastnight with no signs of major damage..no glitter in the oil or chunks of metal, just black..
