I just bought used PRC 5.3 Stage 2.5 heads that had 2-3k on them but the car was running a little rich, does the build up on these valves look too bad?

 

 

Looks like 1 bank was a little rich but nothing to worry about they are goin on your car now

 

Maybe cleam them up alittle. I would set them upside down and pour/spray some decarb into the chambers and let it sit for a few minutes. Like he said. No worries, going on your car now. I would feel better knowing that they are cleam but in reality thats probably only a feeling and will have nothing to do with performance.

Have fun with them.

 

thanks


working on cleaning then it's just a royal pain lol

 

here are some pics of the valves
