PRC 5.3L 2.5 Heads? I was told that the head's didn't have cnc'd chambers but I just got mine and they do, anyone else's have cnc'd chambers? If so, has anyone CC'd them for chamber volume?

I have a set undecked but never measured the cc's though. If you got them from TSP, and you are using a MS3 or MS4 they recess the valves a little for better PTV clearance. I think the castings undecked have 64cc chambers, but don't quote me on that.

As stated, the 5.3's do have CNC'd chambers, the LS6's do not. Let us know if we can help with anything else on your setup!

Thanks for clearing that up from the source, heads look great BTW, it looks like the bowls were hand blended? I did find a extra lock just floating around though :-O

There is a bit of blending done in the bowl area. Good eye!
