Baisley Spring & Plunger?
I'm installing a Andrews camshaft conversion, going to hydraulic cam chain tensioners on my "04 RK 95". while I'm apart should I add the Baisley Spring with the polished plunger to the '07 & up cam plate?

Not necessary; the upgraded pump is more than adequate. I would advise that you pull the relief valve from the new cam plate; they have been known to stick from the factory. Take it out and polish it up with a Scotchbrite pad or some fine steel wool and make sure it moves freely in the bore before installing the cam plate.

Early TC88s used to idle at 2-3 psi; sometimes the pressure light would even blink on and off; they would do that for 100K miles.

So, if you think the 8% increase in flow and the 22% increase in scavenging is worth the $135 or so cost, then you have answered the question. However, there is a better question and that is do you NEED that increase in flow and scavenging. I think not but that's your call.
If you are changing cams, don't forget to change/upgrade the inner cam bearings.
