I have a ticking noise thats apparent at idle and increases with rpm's on load, i caught a thread that mentions bad lifters and to check the vacuum pressure.

"Vacuum pressure" is kind of an oxymoron, isn't it? 
Vacuum is the opposite/absence of pressure. You need a vacuum gauge hooked up to one of the vacuum ports on the intake or you can use a scanner or diagnostic software to observe the MAP reading and then convert it to vacuum.
