When guides wear ou they can leak oil and have problems controlling the valves.
That cam should be fine as long as the valvetrain geometry is set up properly. You can run that cam with stock rockerers. The problem with them is they start to have problems being able to be set up properly around .600 lift.
aftermarket rockers help fix this. Vettenuts has a very good write up about setting proper wipe pattern. Quantitating the amount of wear that is incurred from an improper setup is difficult. You may have one setup where it may be really close and another where the rocker tip is digging into the side of the valve.
Vsocks1 covered the trickflow part.
You can have the guides replaced in any head. I was going to have a set of 8mm guides installed in a set of lt1 heads. It was going to cost $152 or $9.50 per guide.
