lq9 w/ 5.3 and tsp 233/239 in the middle of my build and my friend has a set of 5.3 heads for sale.... dont want to buy the heads and waste his time shipping them to me if im going to have PVC issues. so i have a few questions
will i have PVC issues with the TSP 233/239?
around what compression ratio will those heads yeild?
lastly if the top 2 areas are safe what could i expect to put down n/a and on a 125 shot?

It depends if they are milled or not. Have him measure the valve drop and see what it has. That will tell you if the cam will clear or not. You might also take a look at some 2.5 LS6 heads. They will fit the bore better and there won't be a huge difference in compression.
