My engine is out of the car right now because of Ti rod failure, I'm planning on getting some heads from Ironmask but I'm not sure I'll be able to get them before next season starts here in Michigan. So for the time being, I'm getting new guides put in the PRC 285s and I have a set of TSP roller tip rockers to run with them, that hopefully will help with guide wear.

Interesting, I have an '18 built TSP motor with the 285s, + .650" cam and stock rockers. Sitting at about 4k miles so far since installed. What were your initials signs of guide failure? Ton of oil consumption?
