All sounds good, already smiling more

No worries Tunnie, I do it all the time 
Would you worry about the lifters then as Omegav6cd suggests Mark? I didn't really want to be pulling the head to peices to be honest..
It is a fundamental rule that when you change cams you change lifters the reason being that when an engine has run for long time the lifter and the cam have settled to match one another while wearing in. Now if you introduce new cams to old lifters then this process of bedding in will re-occur With the danger of affecting the radius of the lifter(lifters are not flat) and preent them from rotating as they supposed to. if this happens the wear will be accelerated. This is the reason why serious engine manufacturers alwasy Kit these parts together as s[are parts. This is the technical reason, but apart from that it is a damn good idea to do it while at it because at 107k miles you don't know when a lifter will decide to go making your nice engine sound like a flamengo players clapping.
Hmmm
Based on that advice then, if I've got cams that have been used for star ship mileage, is it going to hurt them using new lifters? Over the lifters that they would have originally worn with?
And - sets of 32??! Looks like I'll be saving for a bit before I put these in, the last thing I want to do is ruin the engine.
From what I've heard.. these cams are meant to be in super condition... I think you'll be fine
If your lifters are not noisy.. I would just inspect/clean them as you wish.. and re-fit with the 3.0 cams
Project Elite, a couple of lifters went back in the wrong places... and it's running sweet as a song..
Just put the cams in, and enjoy the right foot
